Military grade sonic weapon is used against protesters in Serbia

observationist

Serbia had the LRAD systems on hand, after buying them in 2022, most likely from Genasys, but possibly from HyperSpike.

https://genasys.com/lrad-products/

It's a legal gray area in Serbia where the use against civilians isn't explicitly forbidden, so they're playing fast and loose and moving fast to crush opposition. It's better than troops just gunning people down, but for a modern, supposedly civilized country it's horrible to see.

The people in power are the type of people that use their power in these ways. The US shouldn't be supplying them. We're not the world police, we don't need to enforce global norms, and we shouldn't be selling hyperoffensive mass crowd control technology. They should be limited to Temu LRAD, or their LRAD at home; we shouldn't be providing them S-Tier dystopian authoritarian kits for DIY oppression.

The people that profited off of this are a special kind of evil. We shouldn't be outfitting dictators, gangsters, or warlords.

But, greed is good. The dollar is king. This is what happens when incentives and principles don't align.

> It's better than troops just gunning people down

Except you're far more likely to use it.

This is why cops don't shoot to "injure" instead of kill (also, it's hard enough for them to hit center of mass in a tense situation; there's no way they hit a leg.) It's lethal force. Which means that for its use to be legal, that person has to die because they are an imminent lethal threat to others. If injury is sufficient to resolve a situation, they weren't an imminent lethal threat.

Tasers started out as a way to temporarily incapacitate someone so you didn't have to shoot them. Now they're being used as compliance and corporal punishment devices.

Lots of videos out there of cops ordering people to do something while shocking them with something that makes their entire body lock up and is extremely painful.

They know the person can't do what they want them to. "Stop resisting!" while tasering someone is the cop version of "stop hitting yourself!"

During the BLM protests US police realized that they could do serious injury with "nonlethal" rubber bullets. Several people lost eyes including a journalist.

kazinator

> If injury is sufficient to resolve a situation, they weren't an imminent lethal threat.

That requires more explanation.

An injury could render someone with lethal intent and capability unable to perform.

camilo2025

You are aware that these LRAD systems have been used against US citizens, aren't you?

Police also regularly use tear gas against US citizens. These are weapons that would violate the Geneva convention, but we're okay with them to disperse a crowd.

killjoywashere

Chemical Weapons Convention (CWC) (a follow-on to the 1925 "Geneva Convention") allows for the use of riot control agents (like tear gas) for law enforcement purposes.

https://www.opcw.org/our-work/what-chemical-weapon

sa46

The Geneva Convention bans all chemical weapons. Part of the rationale for a total ban is to avoid escalating to more dangerous chemical agents. Helpful r/AskHistorians thread:

conception

Generally if you do it to your own people the world is fine with.. just about anything.

mightyham

It is an obvious fallacy to conflate the usage of tear gas canisters with the usage of mustard gas in WWI. They differ drastically in amount/concentration, area of effect, and long term health risks, thus should be treated differently in considering their usage.

Tear gas clearly sits on a spectrum of non-lethal arms with various other options that are more or less harmful. While it's entirely fair to criticize its use on a case by case basis, insofar as disorderly public gatherings can have varying levels of violence/destruction, it would stand to reason that some instances warrant the use of tear gas.

BobaFloutist

How do you feel about the defensive use of pepper spray?

tbrownaw

> These are weapons that would violate the Geneva convention, but we're okay with them to disperse a crowd.

Isn't that a category ban that came out of a couple specific members of that category that were used and had particularly nasty effects? And then countries' domestic law enforcement rules tend to be defined in different terms.

_DeadFred_

24/7 lighting of prisoners so they can't sleep is torture, unless it's the American police and they need to keep the lights on for 'safety'.

Electro shock torture is illegal... unless it's the cops using a taser to get a desired behavior/compliance.

Police use > legally defined torture/war crimes.

laweijfmvo

are they against the Geneva convention because of the direct effects, or because in a war you’d then proceed to kill everyone while they’re coughing?

spacecadet

My American Citizen score card:

LRAD + Tear gas 2009

Still got the exhausted canister from 2009 as a souvenir. Carry a bottle of water, the tear gas rinses out quickly.

They have been used against US citizens in the United States? That is news to me.

If they have been used in other countries against US diplomatic corps that is an act of war.

Now if a US citizen uses a visit to a foreign country to protest against a government they’re on their own. I’m sorry, but US citizens shouldn’t be engaging in that and the US state department has no obligation to protect that condition.

ruined

it's actually quite common. i have personally experienced use of LRAD by police as a weapon.

the first actual use of LRAD by police as a weapon in the united states was possibly in 2009

https://www.aclupa.org/news/2012/11/14/city-pittsburgh-settl...

though it is known to have been deployed but not used as a weapon earlier than that.

The US has also in some places explicitly legalized the use of cars as a lethal weapon against protestors: https://www.nytimes.com/2021/04/21/us/politics/republican-an...

How do you reconcile this statement with the rest of your comment in which you are advocating for enforcing global norms?

K0balt

FWIW there was some nice MILsurp LRAD kit on eBay a few years back. Looked like there was some corrosion but repairable, possibly functional in its current state. Wasn’t the truck sized one, but big enough (about 1m emitter) to do what is seen in the video. Sold for around 3000 iirc lol. I don’t think anyone knew what it was or it would have sold for a lot more. The seller had no idea, or at least wasn’t letting on if he did.

So, it’s not like LRAD is controlled like SAMs or something. Also, pretty trivial to build. Idk what the IP looks like on it , but back of the napkin you can build a 1kw unit for around $7000 buying the parts at retail. The expensive bits are the transducers. Everything else is a few mosfets and MCU/software.

ashoeafoot

The opposition protesting here is 1/5 of the population of the country . Its basically all people. Like 1 million protesting in a country of 5 million , is all voters between 18- 59. Russia is loosing , the rot of oligarchy is dissolving.

observationist

Assuming average age distribution between 16 to 60 in the protesters, that leaves about 3 million non protesters in the same age distribution for serbia, with children and elderly making up the remaining population, which is around 6.7 million, give or take.

That's 1 out of 4 working age citizens hitting the streets - not all people, but a huge chunk. It's safe to say there are going to be a lot of sympathizers in the non-protesters, a lot of people who wanted to protest but couldn't. There are definitely those who support the government, but I'd wager they're less than 15% of the total population, with the rest in opposition, or at least not in support of the government.

The usual tipping point for revolution is lower - if 10-12% hits the streets, it's a strong signal that the movement behind that activity is taking power.

mariusor

Age distribution is rarely "average", whatever you mean by that. See here a quick googled source for Serbia: https://www.populationpyramid.net/serbia/2022/

According to that graph the cohorts with age less than 15 and more than 69 form only 27.7% of the total. Parent was broadly correct.

ein0p

It is impossible for Russia to "lose" in Serbia. The vast majority of Serbs support Russia, and are pissed at their government for not supporting it enough.

gloosx

It is very possible to juggle around with the opinions of "vast majority" like apples. Vast majority will always support the thing which a delicate minority will push into their throats via media.

Kostic

That's a blatant lie. We are protesting because 15 people died in Novi Sad because of corruption, 4 months ago. We want justice.

This is pure nonsense. These protests have nothing to do with Russia, and everything to do with corruption

tonyhart7

the only acceptable condition to use it maybe if there are riot or violence breakout in that area not for peaceful protest

__MatrixMan__

If you were at a protest that was starting to get a bit rowdy and somebody used one of these on you, what would you do? I'd either come back prepared for actual violence, or switch from protest to sabotage.

It just screams "escalation" to me.

JumpCrisscross

> If you were at a protest that was starting to get a bit rowdy and somebody used one of these on you, what would you do?

Leave. The moment it turns into a riot you’re doing damage to your cause. (If you’re in a protest and see hooligans, restrain them.)

KennyBlanken

At protests cops purposefully escalate things by having a cop undercover in the crowd to do something violent enough to justify police attacking the crowd.

They lob a rock in the general direction of their buddies and Bob's your uncle.

Years ago someone caught some campus cops tossing some bricks into the bed of one of their pickups behind their station.

They claimed they'd removed them from a section of sidewalk where they'd come loose and become a hazard. First time I've ever heard of a cop doing something like that...

propagandist

And that is possibly the aim. When the protests turn into violence or sabotage, the state uses that to justify its own violent repression.

s1artibartfast

yes, it is an escalation.

Governance is maintaining public support for the government having a monopoly on violent escalation.

If the government does not have this power, then any person has an individual veto over the rest of the country.

Laws are used to describe how and when individuals can protest.

Philorandroid

Are chemical irritants preferable, then? Or just LEOs in riot gear with rubber batons? There's no amount of pushback or repercussion that a rioter will feel is fair or humane, and the mindset of "I'll turn violent and/or destructive if my participation in civil unrest is punished" is a perfect justification for these systems to exist.

timewizard

It's a weapon meant to deny the use of an area by threatening non-selective permanent physical damage. There are very few legitimate civil use cases for something like that.

Aeolun

Something like protecting the capitol from being stormed by a mob?

AngryData

I don't find it acceptable for any reason whatsoever.

hayst4ck

It's the most important time in human history to protest/fight unchecked power because it's likely the last era of humanity that we are going to be able to.

We are getting to the point where the technology that fuels oppression, including extremely pervasive surveillance, privatized intelligence services with no oversight, scalable AI agents that do as they are told, and crowd "maiming" or other forceful dispersal techniques are growing past the ability to resist them.

Wars historically happened under conditions where people died but the planet was largely left in tact, but we now have 3 countries with the ability to erase entire cities or make the world functionally uninhabitable by humans, which absolutely changes the calculus of war. If you do not have nukes your sovereignty is questionable.

Likewise if the tools to put down crowds, find saboteurs, and weed out dissent is perfected, meaningful dissent can only be expressed through withdrawal and there is no final check on abuses of power where any, instead of some, of the "checkers" of power are left in tact. Anti-dissent technology has the potential for a nuclear moment that fundamentally changes the calculus of protest and I think AI is very much potentially that.

cmrdporcupine

Was expressing this fear to my wife and kids the other day. Ubiquitous cameras everywhere (like in the UK for many years) and other surveillance technology has always been a concern but had scaling limits -- but when you combine it now with the cheap ease of machine learning technologies we have a serious problem.

And then consider drones, mobile devices. And then mass disinformation and/or disruption via LLMs.

As a long time advocate of old school mass action, and a believe in active protest movements as part of a healthy democracy, I have a strong feeling of unease. I've had it since about 9/11, but it's now really bad.

e.g. if you know, with certainty, that heading out to a protest could lead to your instant termination from your job because a drone passed over and took a photo and identified all 100,000 people in the crowd instantly.. would you still go?

Or if having been identified, some malevolent actor could just turn around and mass produce fake content from you and others in the crowd, to discredit you?

Shivers.

archagon

AI also has the potential to detect your every unique tic in a way that humans would be incapable of doing. You could be masked but your gait and other body movements will give you away, or at least place you in a statistically likely pool of suspects.

The funny thing is that most people see this as a feature rather than a bug. Before the 2024 election the policies of most surveillance platforms roughly matched the culture of upper-middle-class Californians, so the argument was "if abusive technology is used to shut down opinions I don't like, I don't see a problem with that". Good luck explaining why such an attitude is a problem.

hayst4ck

"If guns are used to shut down crime, I don't see a problem with that."

Is kind of a cogent argument.

In this philosophically exaggerated isomorphism, you seem to be implying that either criminals and crime fighters should both be equally armed or that crime is largely subjective and therefore enforcement is wrong.

It seems like you're ultimately arguing for anarchy (nobody should have abusive technology -- guns), and therefore no institutions are worth protecting with force. It seems equivalent to believing that everyone will respect the commons in the tragedy of the commons without an enforcing mechanism.

Regardless of how you answer, you have run headlong into the paradox of tolerance, and the problem of what to do when people violate the social contract (https://en.wikipedia.org/wiki/Social_contract), which is at the very core of what this country was founded on.

What "opinions I don't like" are you referring to? It's also worth reflecting on that you're writing on a platform where shutting down opinions you don't like is a major part of it, in order moderate extremism and promote curiosity.

Nursie

> we now have 3 countries with the ability to erase entire cities or make the world functionally uninhabitable by humans

If we're talking the Russia, the US and China then they certainly have the largest arsenals, but there's an order of magnitude difference between the stockpiles of the first two and the third. China doesn't have that many more nukes than France, and only has about double the number of warheads of the UK (though it is questionable how independent from the US the UK's capability is).

And then there's Pakistan, India, Israel and North Korea.

Chinese nuclear weapons, 2025

from: Nuclear Notebook, Bulletin of the Atomic Scientists

~ Hans M. Kristensen, Matt Korda, Eliana Johns, Mackenzie Knight | March 12, 2025

  The modernization of China’s nuclear arsenal has both accelerated and expanded in recent years.

  In this issue of the Nuclear Notebook, we estimate that China now possesses approximately 600 nuclear warheads, with more in production to arm future delivery systems.

  China is believed to have the fastest-growing nuclear arsenal among the nine nuclear-armed states; it is the only Party to the Treaty on the Non-Proliferation of Nuclear Weapons that is significantly increasing its nuclear arsenal.
* https://thebulletin.org/premium/2025-03/chinese-nuclear-weap...

Also, the threshold laid out above was "erase an entire city" OR "make planet unihabitable".

Any nation or group with a first gen atomic weapon can erase a city .. exercising that ability can potentially lead to a greater nuclear exchange between others, particularly if it's unclear what happened and what might be about to happen.

Nursie

Fair enough, thanks :)

I imagine France is now starting to polish everything up more fervently as well, after Macron's speech about putting the nation onto a wartime economy last week, and there are other nations now talking about wanting to be under the French nuclear umbrella...

We certainly live in interesting times, to abuse that old chinese curse.

bpodgursky

China is growing their arsenal quickly. And frankly, more of their warheads may actually work than Russia's.

Nursie

Are they?

I'm not especially up on this stuff, but I haven't seen much about their nuclear arsenal lately. It's not that I doubt you - it would be entirely consistent with their general move to throwing their weight around, sending their warships provocatively near to other nations etc etc.

Even so, when we have a distribution that's roughly - 5k, 5k, 400, 300, 200, 200, 150, 90, 30 - it seems a little odd to draw the line of who could make the planet uninhabitable after the 400!

cnotv

I think this is the last chance for the people in power to stop messing around before US, the people with knowledge, get pissed off and take them down with force, using the technology WE make for THEM.

hayst4ck

They already know words are meaningless and don't count for anything. Democrats have been trying to use words to get their way or even compromise and republicans fully understand they don't have to pay attention to them at all. Threats are laughable. If democrats had any power they would have used it. Their inaction is proof of their impotence.

Words don't matter, only actions matter. "upvotes don't count."

A street presence can barely be mustered.

Also if you start learning about history, you'll learn that "intellectuals" are the first people totalitarians crack down in precisely because of this threat you just made. So by the time you realize you need to make good on your threat, chances are it will be too late. Don't read about the Khmer Rouge killing fields or the Indonesian "communist" purge if you want to have a good day. American exceptionalism is fueling a "can't happen here" attitude that's fueling people's denial about our many potential futures. Inaction means that we aren't influencing what that future is. We are at someone else's whims. History doesn't tell you what will happen, but it tells you what can happen.

You're saying right now you're speaking softly, but carrying a big stick, so they better listen. I don't think you're carrying one, and the republicans purging the old guard and replacing them with loyalists don't think you are either. You're just speaking softly. We all seem to be.

red-iron-pine

to paraphrase another person: if you're posting it online on a public social media channel, it doesn't matter.

the stuff that's going to change the government, for the better or worse, is going to get the FBI and Secret Service on you, and you're not saying on that on the front page of reddit.

every twitter meme that makes the rounds, every sneering HN post is a sign of impotence. if there was real opposition DOGE would be afraid to go to offices. the best the US Dems can do is spray painting a few Tesla offices (save for one in Oregon that had some bullet holes, done well after closing).

The Jan 6th rioters were fascist rubes, but at least they had the balls to go.

Nuclear war is horrible enough without requiring hyperbole. Each of the U.S., Russia and China have the ability to functionally end industrial civlisation as we know it. None has the power to make the Earth uninhabitable by humans (outside hypothetical asteroid redirect capabilities).

No. Just no. No matter what what the thing is. It just isn't.

That's not a reason to NOT protest/fight unchecked power. It just isn't the reason to do it.

energy123

One thing is for sure. These technologies don't make protest or revolution any easier. They give asymmetric power to whoever wields them (the state) against whoever doesn't (a loose collection of angry people on the street without the same tools).

This isn't the 1800s anymore where the most powerful tool was a gun, and you could distribute these symmetrically across state and people to keep the state in check.

Surveillance, crowd control weapons, access to banking, control over media, eventually AI and widespread robotics, have properties that empower the state. In the context of mass protest, the status quo gets harder and harder to dislodge.

None of this matters much while democracy is still existing, but it's a risk that's there. It makes the fall of democracy more of an absorbing state that you can't escape from.

The encryption gives asymmetric power to the people. Tor and Matrix for communications that can't be broken by the rich, no matter how powerful. Bitcoin for free transactions, vpn and torrent for the media etc.

grujicd

Close friend who was on the spot described it as car or plane running towards you, you don't only hear it, you also feel vibrations in the body creating panic and fear.

All demonstrations of LRAD I heard on youtube were with high pitched sound, not a "whoosh" as witnesses experienced last night in Belgrade. Can these devices play any kind of sound?

What is described by victims, and what can be heard on some recordings from last nights, sounds more like Vortex Cannon:

https://www.youtube.com/watch?v=GJpChS-_RJg

user_7832

I’m moderately suspicious of the details some people/articles say. Long story short, there’s 1-4khz audio weapons (LRAD), and microwave/heat based ADS. It appears that both of these were used, a Reddit army vet commented about how that’s apparently the “protocol” as the ADS is strong enough to pick off the last stragglers.

I’m ever so slightly suspicious of the “low frequency sound weapon” aspect because that typically takes a lot of energy (I’m speaking from an audio background). However the reports of feeling uneasy do match that of infrasound… yet typically (based on what I’ve read) infrasound doesn’t have an instant reaction but takes some time for people to feel it.

https://en.m.wikipedia.org/wiki/Directed-energy_weapon has a lot more info if anyone is interested.

grujicd

Earshot NGO analyzed recorded sounds and found 4 of these videos "consistent with Vortex Ring Gun or Vortex Cannon":

https://x.com/earshot_ngo/status/1901661518153781534

Note that many videos didn't record the sound if the phone was further away from that center line.

This is the recording which perhaps captured sound the best:

user_7832

Thank you. Before I saw your reply, I saw this discussion and links on r/acoustics which in retrospect seems to be the best likely answer. It being a cannon (and not a speaker based device) would mean it’s closer to a controlled explosion than a speaker playing (really loud) music.

There’s still the questions of “how is it so small” (apparently) but at least some aspects are answered now.

elaus

Even without knowing the background of those protests: It is heartbreaking to see a crowd of peaceful people (seemingly during a moment of silence) being attacked by their own country and fleeing in panic and pain.

aznumeric

Another video, from a different angle:

https://www.reddit.com/r/serbia/comments/1jchks6/novi_snimci...

Please take into account that this occurred during the fifteen-minute silence observed by the protesters in memory of the fifteen victims of the accident, which the protesters blame on the government corruption and which was the very reason for the start of the protests.

crooked-v

I've seen some theories that it was actually an ADS (basically a low-power microwave beam, immensely painful but tuned to be just under the threshold to actually cause visible burns), since there haven't been any reported cases of permanent deafness yet.

The student organizers in the crowd did an incredible job clearing people out of there before the police could escalate further and cause more mob-crowding panic deaths.

It really isn't smart to do this kind of thing.

Once an organization actually attacks you, it's very easy to decide that any legitimacy they view themselves as having is irrelevant and to come back next Monday with mortars and machine guns.

captainkrtek

Reminds me of the escalation seen in the Ukrainian Maidan, went from some heavy handed policing to non-lethal rounds (eg: teargas / beanbags) to BBs to snipers and live firing on crowds.

impossiblefork

Yes, although that was exceptionally irrational, to the point where I don't really feel I understand the events.

It would be rational if you would think killing a few (or a lot of) protesters will intimidate the rest of the country into submission. It didn't, but it could have.

“Winter on Fire” on Netflix is a pretty thorough documentary of events day-by-day, though many scenes are difficult to watch.

Unfortunately, it worked in Belarus.

Estimates are that something like 300,000+ people were out actively protesting just in Belgrade... in a country of 6.6 million people.

impossiblefork

Yes, but polarization is a possibility. You can't know you're the majority, so until violence is used against you, you don't necessarily have a reason to turn the thing into a civil war.

Tadpole9181

Something like 1.6 million people across Serbia were protesting across the country, last I heard. They're the majority.

You're using whataboutism to conflate the Serbian government with an imaginary counter faction. Civil war requires 2+ factions that cannot or will not express their grievances through political means. This simply isn't the case.

Where the heck are they going to get those in Serbia? Weren't they rounded up after the war, especially mortars?

Also that sort of thing tends not to last very long against the regular army, who have a much larger supply of materiel and are better trained. It only really works if the army flips politically against the regime (think Ceaucescu, or less violently the Carnation Revolution).

cue_the_strings

There's a huge amount of weapons hidden away in attics, even after several campaigns to get rid of illegal weapons, no questions asked. There's also a huge amount of it in the region (Montenegro, Bosnia). I used to live first in Serbia, then Montenegro.

I've personally been to weddings in both Serbia and Montenegro, in the early-mid 2000s, where they fired full auto weapons with live rounds into the air. AK variants and such. I remember us kids collecting shell casings and stripper clips.

I'd say that it's mostly handguns and hand grenades, some AK and SKS variants, obsolete 40s-50s SMGs given out to territorial defense decades ago, some bolt action rifles and some Zoljas (anti tank rocket) and AP mines from the war.

I remember a guy in Podgorica, Montenegro (local football hooligan and drug dealer) firing a Zolja at a department store at night. He had obtained it for 200 euros in Belgrade, Serbia and "had to try it out". [1]

I also remember them catching a 15 year old with an AK in 2017 in Podgorica, Montenegro. [2]

I loved frequenting the local flea market and you could regularly see stuff like helmets for sale, also some magazines (I remember seeing one for an MP40 or similar SMG). I also witnessed a transaction, a guy buying a small pistol from another guy at the flea market. The gun quickly changed hands and dissapeared in his jacket, but I saw it beyond doubt.

Anything else I could write would just bring into question my credibility, so I'll keep these stories for us who lived through it. It recently happened to me that I started quesioning my childhood memories (age 8 or so), like "did that really happen or did I imagine it", so I asked people I remembered were there with me, and yep it sure as hell did. I even forgot some details and people involved. But I'd have a hard time beleiving it if I heard it.

Also bear in mind that a lot of the people who have these weapons actually support the government and loved Vučić's old party from the 90s. For example, one of the people firing an AK at his son's wedding was a policeman, and his grandson is now a policeman and Vučić sympathiser in Belgrade.

I'm pretty sure that's not actually how power or legitimacy work anyway.

Once they're shooting at you, or going after you in some other way, that legitimacy etc. is irrelevant, simply because they're going after you.

The solution is then always an organized military response. This applies whether it's your government or somebody else's.

> The solution is then always an organized military response.

In actual history, not always, and not that often.

Case in point, for example, the Peterloo Massacre: https://en.wikipedia.org/wiki/Peterloo_Massacre

   took place at St Peter's Field, Manchester, Lancashire, England, on Monday 16 August 1819. Eighteen people died and 400–700 were injured when cavalry charged into a crowd of around 60,000 people who had gathered to demand the reform of parliamentary representation.
the response to that, from the general public, was general outrage, mocking of government, but no "organized military response".

The immediate effect of Peterloo was a crackdown on reform. The government instructed the police and courts to go after the journalists, presses and publication of the Manchester Observer.

  For a few months following Peterloo it seemed to the authorities that the country was heading towards an armed rebellion. Encouraging them in that belief were two abortive uprisings, [..], and the discovery and foiling of [..] conspiracy to blow up the cabinet that winter.

  By the end of the year, the government had introduced legislation, later known as the Six Acts, to suppress radical meetings and publications, and by the end of 1820 every significant working-class radical reformer was in jail; civil liberties had declined to an even lower level than they were before Peterloo.
The urge for reform increased, resolve stiffened, and eventually (after some time) change came about.

  Events such as [ ..these.. ] all serve to indicate the breadth, diversity and widespread geographical scale of the demand for economic and political reform at the time.

  Peterloo had no effect on the speed of reform, but in due course all but one of the reformers' demands, annual parliaments, were met. Following the Great Reform Act 1832 [ ... ]

you are stating this with confidence but it doesn't sound at all convincing - where are you getting this from?

aggressive crowd control measures have been used very often and they almost never result in an armed rebellion. that's just nonsense. There are many MANY levels of escalation left for both sides - as well as the real expectation of behind the scenes diplomacy and within-the-system politics.

like really, are you just fantasizing about a balkan civil war because it's exciting? or are you trying to get more people to think that civil disagreement may as well be considered warfare? just what are you on about, mate?

This strikes at the core of the idea of solidarity.

If you see injustice but do nothing, you invite the same injustice on yourself.

Injustice at it's core is an arbitrary execution of power, so suffering injustice anywhere is to let power stay unchecked which communicates that there are no consequences for abuses of power, which only invites more abuses of power.

If there aren't consequences for power being used against others, there won't be consequences for power being used against you.

I wonder how the engineers and scientists who contributed to that less-lethal weapon feel about it.

Probably enjoyed working on cool sci-fi shit. Invisible weapons are pretty cool -- though I think conceptually the heat ray class (https://en.wikipedia.org/wiki/Active_Denial_System?useskin=v...) is cooler than the LRAD class. How they're used or should be used? An unimportant question in the face of coolness. Then there's just basic pride in good engineering or craftsmanship that can help spark joy in whatever one is working on, from weapons to some hairy enterprise legacy ball of mud you're slowly making improvements to. A silly quote I've always liked, from Nathaniel Borenstein: "It should be noted that no ethically-trained software engineer would ever consent to write a "DestroyBaghdad" procedure. Basic professional ethics would instead require him to write a "DestroyCity" procedure, to which "Baghdad" could be given as a parameter."

I will always have more respect for prostitutes, pimps, drug dealers and thieves than people working in "defense".

Even an exceptionally violent and prolific gangster could never come close to contributing to the suffering of as many people as your regular MIC employee, no matter where they're employed.

If I were to try to imagine how I could realistically inflict the most suffering on the world, the clear answer would just be "get a defense job", I really couldn't do any worse than that no matter how hard I tried. Maybe starting a defense company would be worse. Team work makes the dream work, as they say.

That's a very broad brush. You could use a roller, with handles on both ends for stability, if your surface is so uniformly flat.

There are "dual-use" systems, and there are systems that are only weapons.

There's also technologies and basic research, but those are different matters.

LRADs have been used against protesters in Australia, New Zealand, the United States, France, and Germany.

photodeveloper

I assume it was used to disperse riots, in Serbia it was used as people were standing peacefully, observing 15 minutes of silence.

luckylion

A lot of the uses in Western countries weren't even to disperse anyone, they were used as giant speakers to broadcast messages, e.g. during Covid in Germany.

It's crazy to compare that to what seems to have happened in Serbia. It's like saying "Carter has used a hammer, too" when commenting on a murder, and leaving out that Carter used the hammer to build houses with Habitat for Humanity.

macintux

"whataboutism" is pernicious, widespread, and devastating to civil society.

pjc50

The difference between a peaceful protest and a riot is usually just a matter of who's doing the reporting. Or whether the police have bothered to plant a provocateur in the crowd to throw the molotov that justifies the police violence.

Famously: https://www.bbc.co.uk/news/uk-england-south-yorkshire-278930... - which side started the violence? Was the footage shown out of order? Was the state broadcaster complicit?

The idea that protest provocateurs are all 5th column police plants is, uh, wrong.

Is there any counter measure for this?

Hardcore hearing protection?

Noise cancelling headphones?

Handheld sound insulation "shield"?

zozbot234

Use some thick metal plate as a shield and let it reflect the sound back towards the source, most likely. Or something foamy, like mattresses or the like, to just attenuate it. But I don't think any of that would protect you if you're facing 160 dB (though it would indeed be useful if you're farther from the source); the appropriate tactic then is indeed to disperse uniformly over a larger area and make it infeasible for your adversary to launch a concentrated attack. (After all, this is how actual present-day military tactics copes with the existence of much older "area denial" weapons, such as machine guns, tanks etc.) Your protests should then become more "hit and run" in style, relying on highly visible gimmicks rather than mere physical presence to demonstrate continued support.

lor_louis

That's the exact same circumstances that lead to the development of guerilla warfare. I don't know how you'd go around creating a "highly visible gimmick" that has any lasting impact though.

zozbot234

The point is to simply demonstrate mass support by any means available. You can do it by gathering as a large crowd, but when that becomes a vulnerability your tactics must evolve somehow.

amatecha

Dunno, ask Tesla owners how they're feeling about driving their vehicle and parking it, lately. On that note, ask Musk how he feels about the trending direction of his stock value. The highly visible gimmick of swastikas spraypainted on cars, torched charging stations & Cybertrucks, etc. seems to have an effect. Probably a lasting one, though that remains to be seen of course.

impossiblefork

Once there's violence targeting you, the solution is to bring real weapons and resolve it using ordinary military tactics, that is, you kill the operator.

mmooss

That sounds bold and exciting, but it's clearly false and terrible advice.

Violence, like warfare, is politics by other means. Every expert knows that law of warfare - the first law of warfare, in a sense - that it ends when and only when there is political agreement. Even in warfare, violence just buys time and changes your political position.

In countries with rule-of-law, you can use the political / legal system to stop the violence and hold accountable the perpetrators. In countries without, the only solution is political.

It's also well-established that non-violence and other tactics can be quite effective. While if you attack back and injure others, your credibility and legality is gone - nobody will listen to you or pay much attention to 'they started it' (which the other side will dispute anyway).

impossiblefork

Once there's violence targeting you, the politics is over and a different kind of problem solving begins.

If someone has attacked you and there has been no apology or attempt to solve the situation, he must be eliminated. Once he's done it, he may well try again, in which case you might die. Better then to get rid of him.

>And how we burned in the camps later, thinking: What would things have been like if every Security operative, when he went out at night to make an arrest, had been uncertain whether he would return alive and had to say goodbye to his family? Or if, during periods of mass arrest, as for example in Leningrad, when they arrested a quarter of the entire city, people had not simply sat there in their lairs, paling with terror at every bang of the downstairs door and at every step on the staircase, but had understood that they had nothing left to lose and had boldly set up in the downstairs hall an ambush of half a dozen people with axes, hammers, pokers, or whatever else was at hand? After all, you knew ahead of time that those bluecaps were out at night for no good purpose. And you could be sure ahead of time that you’d be cracking the skull of a cutthroat. What about the Black Maria sitting out there on the street with one lonely chauffeur – what if it had been driven off or its tires spiked. The Organs [Soviet state institutions] would very quickly have suffered a shortage of officers and transport and, notwithstanding all of Stalin’s thirst, the cursed machine would have ground to a halt!

If…if… We didn’t love freedom enough. And even more – we had no awareness of the real situation. We spent ourselves in one unrestrained outburst in 1917, and then we hurried to submit. We submitted with pleasure! … We purely and simply deserved everything that happened afterward.

The operator deserves to be killed for this. Stop defending evil

seabass-labrax

"Attack is the best form of defence" is a well-grounded doctrine, but it's not mutually exclusive with protecting yourself. Armies use armoured vehicles even though armour-piercing shells exist, for example.

It's also not always necessary; actively using force against the authorities would essentially be the start of a civil war, and personally I don't think starting a civil war is more likely to result in change than peaceful protest. For instance, Serbia is to some extent reliant on the EU, and has expressed an interest in joining. That should force the current government to reconsider and crack down on corruption much better than an attempted coup would.

Full disclosure: I have never been to Serbia and this is just my personal feeling. But for expressly peaceful protests to seamlessly turn into a full-blown revolution, and a successful one at that, seems incredibly unlikely to me.

impossiblefork

Yes, but these kinds of systems are not actually very good as military weapons. They are easily countered by simply shooting the operators.

martin-t

I fully support targeted use of violence against oppressors and aggressors but it needs to be said that materialized (as opposed to threatened/implied) violence only works if you are able to deliver sufficient amounts of it.

Up until that point you need to paint yourself as the victim (the just/right/good side) to get more support to deliver more violence later what the time comes to materialize it.

Premature materialization leads to the oppressor/aggressor painting _himself_ as the victim and you as the aggressor. And because most people are uninformed, not terribly intelligent and conditioned to prefer peace over justice, they are more likely to take his side.

impossiblefork

Yes, but you probably only need something like a 1000 men to get something like Mariupol. That of course does require all of them to be ridiculously resilient, but I think you can learn that.x

Think of it like this instead: if those who run countries or otherwise have power over people know that they if they attack people risk a proper response, then all such people who are sensible will refrain from violence.

If things get too out of hand there's always the possibility of calling an election.

Defensive measure are also enjoyable as they give an increased tactical field - as to put it, they increase the luck area.

ta1243

impossiblefork

No, he's probably just around the corner, having just set up the speakers and put on his hearing protection.

malfist

The report I read said it relied on bone conduction, so hearing protection wouldn't do a whole lot. Only things that can attenuate low frequency sounds before it gets to the ear. So muff style headphones might work, or mass

wl

It's not so much that LRAD relies on bone conduction to inflict pain (and sensorineural hearing loss!), but that the sound levels are so high that even if you block the air conduction route with earplugs, the bone conduction route (approximately 30 dB of attenuation compared with air) still might deliver enough sound to the inner ear to cause pain and hearing loss.

This kind of thing is a problem on aircraft carriers, where people working on the flight deck are so close to loud jets that no amount of conventional hearing protection will adequately conserve hearing. Creare has been working for the last decade and a half on special helmets for the US Navy to overcome this issue, resulting in the HGU-99/P Hearing Protection Helmet.

gizajob

Ear muffs aren’t going to do much against 160dB

red-iron-pine

to put a finer point on it: decibels are logarithmic, e.g. a tenfold increase.

as in, an increase of 10 decibels corresponds to a tenfold increase in sound intensity.

this means 160dB is a lot. a loooooooooooot

darepublic

Can you have a device which upon detecting the frequency emits some kind of counter vibration that cancels out th attack?

d1sxeyes

This is how active noise cancellation works in headphones. You stick little microphones on the outside of the headphones, then play back what’s picked up through the headphones themselves but with a very slight delay so all the peaks and troughs match up. The problem is that you need to put out sounds at least as loud, and that’s a pretty bad thing to get even slightly wrong if the energy levels are that high.

XorNot

It's not theoretically impossible but it is completely impractical to engineer such a thing - destructive interference has to be precisely matched to cancel out a sound, and if it's not you just get "beats" as the phases overlap.

And that match depends on matching frequency and distance - or having a very fast tuning system, and then you've got to do all this in a device that's not just another LRAD (at which point you're back to "the best defense is a good offense").
