The Vancouver Police Department has confirmed that it has purchased an
MRAD just in time for 2010, a slightly more compact version of the
LRAD crowd control weapon, both of which are produced by the ominously named
American Technology Corporation.
The
LRAD is the squarish spotlight looking device just in front of your local law enforcement official in the photo to the left. The
MRAD has roughly equivalent power and functionality but in a smaller unit size.
For convenience.
The
VPD has
two key media lines about its purchase of the
MRAD/
LRAD. First, that they didn't buy it for the Olympics. Second, that they bought it as a public address system.
To see what a public address system looks like, check out the
SoundCommander 3500. It's at least $5-$10k cheaper than an
MRAD (which runs $20-$30k at a minimum), and sends sound out in all directions so the "public" can hear the "address".
[Note: VPD announced subsequent to this post at a press conference that they purchased this device for $17k used. They "don't know" who they bought it from. See portions of the press conference yourself here. Many classic lines, like "As you can see, it looks nothing like a gun."]To see what a public address system does not look like, check out the
MRAD specifications and functionality. It is designed to send out sound in a "tube" at a specified target where sound levels drop off dramatically outside of the tube. Check out
this great demonstration of the drop off effect of the LRAD, and how it was designed this way, in the linked Youtube video
at 2:15.
No time to watch a video? Read about the drop off effect for yourself on the
ATC website: "The directionality of the LRAD device reduces the risk of exposing nearby personnel or peripheral bystanders to harmful audio levels."
Right, and also reduces the possibility of peripheral bystanders hearing your "public address." If you had to design a device that amplified sound dramatically but was less effective at communicating with a large dispersed crowd, you'd be hard pressed to do so.
The other key difference between the
SoundCommander and public address devices of its ilk and the
MRAD is that only one can be used as a crowd control weapon to inflict pain on non-compliant protesters. Guess which one?
You guessed it, it's the one that wasn't purchased for the Olympics by the VPD.
For footage of the MRAD in "get the hippies" mode,
check out this scene from Georgia, Vancouver's model of democratic rights, at about 1:10 into the BBC news piece.
As for the suggestion that the VPD didn't buy this for the Olympics, it's hard to even know where to begin.
