    So… how portable could this solid surface be? Is it a crime yet to redirect sound waves at a police officer? Should we assume they wear ear plugs?

    Pretty awesome stuff. For all the complaints the teabaggers have they must be pretty pleased that

    1) They can carry weapons at Town Hall meetings and through a combination of their show of ‘strength’ and heckling pretty much negate said meetings and

    2) For all their whining aboutbeing oppressed the really nasty stuff is still reserved for left wing affliated protestors.

    The more things change huh? Why not just declare that from now on the free speech zones for leftie protesters ends at their front door?

    @ 11

    You think a FEW of them got off on it? I bet it was all they could do to stop themselves from running over and tasering the fuck out of them afterward.

    Seriously, what’s the difference between this and using water cannons? Would they USE water cannons? No, because that’s messy and you can SEE the pain. This way, it looks a lot better on the news PLUS the police department gets to justify money spent on a sonic cannon. I’m sure the tax base who paid for that one feels very satisfied now that another “ca-raaaazy G20 protest” went on without an unlawful assembly.

    I’m a fan of the police. I am. They keep people from breaking in to my house, they keep people from smashing me on the freeway, and they found someone who stole something from me one time. All stand-up, honorable things. But I dislike the police when they do things like this. It doesn’t take a psychologist to know what’s going on here and the motivation behind this type of force. All I’m sayin’.

    For those of you who feel that this device was an inappropriate way to break up the crowd*, what method would you have preferred? No one seems to like it** when the police actually comes into contact with crowds like this (see London).

    I’m also confused by why people have a problem with the police being in riot gear (be it black or pink or whatever colour) in this kind of scenario — sure, maybe 90% of all protests are peaceful, but do you honestly think that the police will have time to go home and change if people start tossing “mollies”?

    That being said — I wish someone could give me a coherent set of grievances that the G20 protesters were actually protesting about.

    *whether or not the crowd should have been broken up is a different discussion. If the gathering was illegal (and you feel it should have been allowed), then the problem is with the law, not the people entrusted with enforcing it.

    **I’m willing to bet that this holds true for protesters and police officers alike.

    Now that this has been used once on protesters, the next time, they will come with ear plugs. It will be the people who just happened to be in the wrong place at the wrong time who will end up with the permit hearing loss. To me, that makes this unacceptable. I don’t know enough about the situation to know if the protesters, deserved to be read the riot act or not but I would think that the police have a responsibility to protect non-protesting members of the public to the best of their ability while dispersing illegal crowds.

  47. BdgBill says:

    If they were looking for some people to test a new pain weapon on, they couldn’t have chosen a better group than G20 protestors.

    These people make the crowd at an Arkansas Monster Truck rally look like participants at the TED conference.

    I’m convinced that 98% of these people have not the slightest idea what they are “protesting”.

    @ bdgbill:

    Wow, this sure is all over the news. ;p

    Behind every mask is a human face and I can’t help but wonder what the expressions on those faces are.

    Are any of them thinking this might be a little extreme? Surely some have to stifle at least a little doubt.
    Or are they all thinking of that time they had to negotiate for five hours with that crazy father of four who was threatening to blow up his family with a cylinder of compressed gas (a story told to me by a police officer I sort of know) or about the training they go through that drills shooting an assailant in the head first time (told to me by a family friend who was a CID officer in London at the time); both stories in response to my eager questions about moderate action.

    So you wanna be a cop huh? How do you feel about clubbing hippies? Hmm? Oh. They’re ALL hippies son.

    I want to humanise them but I’m spending a lot of that good humanising energy just keeping myself from getting angry.

    ‘then the problem is with the law, not the people entrusted with enforcing it.’

    The problem is when you PROSTEST against a LAW the ‘people entrusted with enforcing the law’ alway seem to show up, or am i the only one having such ‘bad luck’

    and i still DO have a problem with the 145dBSPL and permanent hearing damage.

  54. AirPillo says:

    We’ve come an awfully long way forward since what happened at Kent State, but law enforcement still needs to start backing off a lot more.

    Having officers nearby, but not interfering, in case of a problem is simply prudent… but they desperately need to stop deliberately trying to break up protests.

    Even if a small number of people were being rowdy among the crowd, I wouldn’t like seeing this kind of thing. Everyone else there is still entitled to the presumption of innocence and the preservation of their right of assembly.

    Save the riot gear for actual freaking riots for God’s sake.

    It’s designed to be so loud that it rattles your ribcage and bones — plugging your ears might prevent damage but you’re still going to suffer when it hits you.

    Looks like these are the high-tech versions of the water cannons used against blacks and blacks-sympathizers.

  60. sparklemotion says:


    The hearing damage is unfortunate. I’m willing to bet that there is research ongoing as we type to find some way to be equally obnoxious, but without causing permanent damage. This device is intended as an alternative to physical force (by which I mean one-on-one combat), water cannons, tear-gas, etc. For now though, I’d really like to hear what better alternatives are.

    The reason why the enforcers always seem to show up is that large crowds of angry people tend to also attract the kinds of people who will use the protest, however legitimate as cover to break other laws. When people who intend to peacefully protest work with the law to get the appropriate permits, etc, the police can then expend their energies keeping the anarchist assholes (probably 0.01% of people involved in something like this) in check. This is why the permitting process exists, not to stifle free speech (I will give you however that this is a very fine line to walk).

  61. danlalan says:


    I saw a show about these things a while back, and they are actually pretty complicated. They collimate sound into a fairly narrow arc (15-30 degrees) and that is tougher than you might think. They are expensive toys. ($28,000)

    “Carl Gruenler, former vice president of military and government operations for American Technology Corporation (and who now runs a company making a competing device), says that being within 90 metres (98 yd) of the device is extremely painful, but its use should be limited to 270 metres (300 yd) to be effectively used. He concedes that the device is powerful enough to cause permanent auditory damage, but that it is only meant to be used for a few seconds at a time.

    Countermeasures may include the use of passive hearing protection (earplugs, headsets), which may bring the sound down to ineffective levels. In addition, sound could be reflected from a solid surface, and redirected back to the originator.”

    at about 30 seconds, you see a girl on her bike about to ride about to ride away gets an unexpected push from behind, nearly off the curb.

    the commentator says “look right here, the police are forcing the cyclists to move.” As she gets off her bike and tries to proceed she is pushed with a baton and nearly falls over her bike she reacts and, as I see it, attempts to “force the police to back off with their unreasonable request to move faster than the people in front of you.” the crowd she was in was moving, complying with the instructions. I don’t understand why the cops had to keep pushing everyone.

    i hope she wins big.

    These cops should learn from the SQ. Up in Quebec the last anti-globalization protest had cops dressed up like ‘anarchists’ hurling rocks at the riot squad. It’s a good way to ensure the heavy cannons are at the ready next time a bunch of grannies decide to feed the poor or something. Just don’t wear police boots while doing it.
