Wired's Danger Room has the original story with links to videos.
Watch and learn, because we are next.
Here's the main video, which shows tear gassing and the use of water cannons. There's so much tear gas that at one point the reporter, who is well behind the police line, begins choking and has to put on a mask.
A video which better shows the use of the acoustic weapon:
Now, I really know very little about the weapons in question. I have posted links and videos which is essentially all the information I have. This is an important subject that concerns this community, and I was hoping for intelligent discussion pertaining to the subject matter from people who have more information on it than I do.
Several people have preferred to pick nits about the "lack of substance" in the diary, which is a roundabout way I suppose of admitting that they have little else to add to it themselves. However I am nothing but accomodating, so at the request of all those whiners I hereby add the following "substance":
Trolls who are hanging out bait waiting for me to comment so that all your sockpuppets can TR me... while you're waiting, by all means hold your breath, too. You know who you are, and so do I.
Incidentally, can any of you think of any particular groups of people who would very badly want to discourage conversation on this particular subject? Let's add some more SUBSTANCE here!
