PITTSBURGH (AP) -- Police ordered protesters to disperse at the Group of 20 summit last week with a device that can beam earsplitting alarm tones and verbal instructions that the manufacturer likens to a "spotlight of sound," but that legal groups called potentially dangerous.

The device, called a Long Range Acoustic Device, concentrates voice commands and a car alarm-like sound in a 30- or 60-degree cone that can be heard nearly two miles away. It is about two feet square and mounted on a swivel such that one person can point it where it's needed. The volume measures 140-150 decibels three feet

“It’s not a sonic cannon. It’s not the death ray or anything like that,” Putnam said. “It’s about long-range communications being heard intelligibly.”

Oh, Ok.

I knew the day would come that these so-called non-lethal methods would be employed against civilians in America.

Police said they used the device last Thursday to issue prerecorded warnings to disperse when hundreds of demonstrators, including self-described anarchists, without a protest permit held a march that threatened to turn violent.
I hate "self-described anarchists" (or, rather, I despise them) as much as the next guy. But this is not right. This should not be happening in the streets of American cities against American citizens.

Look at how easy it is for police to perceive that a situation "threatened to turn violent".

They've accused grannies at Tea Parties of "threatening to turn violent".

This is really bad. In a just world, he chief of police would lose his job, his citizenship and be deported to ChavezLand, where I'm sure he'd be more than welcome.

On-site observations that I have read or seen indicate that there were 4 policemen for each protestor, and any claim that a group of 400 students Friday night on the lawn of the campus of the University of Pittsburgh was “threatening to turn violent” is nonsense. A tear-gas like container was thrown into one dorm where other students were just watching from above, and one girl was taken to the hospital after an asthmatic reaction to the gas. There are other reports that the number of unidentified people actually involved in breaking the 12 shop windows is approximately “one” and that could have been an agent provocateur, but broken glass was about the only thing I saw being reported on the Pittsburgh TV station that Thursday.
