Chicago Police plan to use long range acoustic devices, or sound cannons to control crowds for the upcoming NATO summit. The LRAD emits sounds that are painful and can damage the human ear.

Long Range Acoustic Device to Be Deployed in Chicago NATO Protests

By Paul Meincke, ABC7 Chicago

13 April 12

 

hicago Police are taking lessons learned in Pittsburgh to help control crowds for the upcoming NATO summit.

Police plan to use what's called a long-range acoustic device to keep crowds from getting out of hand. ABC 7's Paul Meincke learned more about the device and what worked and didn't work in Pittsburgh.

The G20 Summit in Pittsburgh in September of 2009 has been called the most peaceful of modern day global summits. There are doubtless many reasons why arrests and property damage were minor compared to other host cities. Police say their intelligence paid dividends. Some protestors say the city purposely dragged out the permitting process for marches making it tougher to organize. And there is also Pittsburgh's layout: a compact downtown that come summit time was filled with riot-control police.

There was indeed a lot of security. Pittsburgh has a police force of around 900 men and women, so for summit duty they recruited officers from other law enforcement agencies, including Chicago.

There were protest marches -- some with permits, some without. The largest was a march across a downtown bridge within sight and sound of the G20 meeting. The overriding message from the thousands involved was spend less on war and more on human needs.

There were no clashes, no arrests in that march, but there were other confrontations.

Pittsburgh used what's called a long-range acoustic device for loudspeaker dispersal orders, followed up by high-frequency, potentially painful audio chirps.

Pittsburgh's use of the LRAD was the first time that machine has been used in the U.S. for crowd control.

"I'm not gonna talk much about the LRAD because we are in litigation over it, but we did use it as a tool to get the message out," said Pittsburgh Public Safety Director Mike Huss.

There are still unresolved lawsuits over Pittsburgh's use of the LRAD and other arrests that protesters say took place without provocation. But the total number of arrests was less than 200, a mere fraction of what other G-summit cities have seen. And property damage was minimal.

From a policing standpoint, Pittsburgh has a couple things that work in its favor. It has hills and it has rivers.

Bridges near the convention center were closed. The immediate security perimeter and beyond were well fortified. The Strip District, just outside downtown, was the announced target of some demonstrators, but they never got close because the river is on one side and a wall of police was in the streets.

"One of the residents said it looked like Keystone Cops just preventing the people from coming. They kept shifting as needed," said Becky Rodgers, director of Neighbors in the Strip.

"I have to commend the police department in Pittsburgh that they did do a good job keeping us protected. We had no damage," said merchant Joe Hermanowski.

Chicago has done what every host city has done, which is to look at those cities that have previously held global summits and find best practices. But every city has its own unique challenges.

Chicago Police say they do have an LRAD available for use. It sends out live or recorded messages in a narrow sound beam. So you can hear the messages with clarity several hundred yards away. Police say that is how they intend to use it -- as a communications tool. But it is also equipped to emit those high-frequency alarm tones.

We are concerned about a recent drift towards vitriol in the RSN Reader comments section. There is a fine line between moderation and censorship. No one likes a harsh or confrontational forum atmosphere. At the same time everyone wants to be able to express themselves freely. We'll start by encouraging good judgment. If that doesn't work we'll have to ramp up the moderation.

General guidelines: Avoid personal attacks on other forum members; Avoid remarks that are ethnically derogatory; Do not advocate violence, or any illegal activity.

Remember that making the world better begins with responsible action.

Naturally of course the city of Chicago would be well advised to boot out NATO instead of booting out people assembling for redress of grievances.

Welcome to AMERIKA...

We have become the land of the homeless! the lost and the oppressed!

The message being there is no free speech in america any more. The new military police are seeing to that.

Well, so now America has to use physical, brute force to show how peaceful America is... Apparently we are the model for dictatorial fascist power.

Hummm, I think Obama is still president, and If I recall he has been the one to militarize the police! But lets ignore this, we need him to be president for another 4 more years, so he can destroy the remainder of the Bill of rights and the constitution! Lets all put on those rose colored glasses and ignore his record of abuses...

The time has arrived when we will have to fight back merely to protect our First Amendment Rights. There must be a way to disable an LRAD device--someone knows how. Find this out and distribute the knowledge. Putting these things out of commission would not depart from non-violence against people and would remove a direct threat which is being deployed against law-abiding people.

There are a lot of highly trained snipers home from the nonsensical wars...maybe they could put a bullet trough the machine.

If this is used I do hope there is a massive class action suit against the authorties for using weapons that hurt the citizens intentionally.

Ummm... can we all just chill out for a minute before running around like a Chicken Little???

The LRAD sound wave can be cancelled altogether through the use of common earplugs. The better the earplugs are at blocking sound waves, the less effective the LRAD is.
Sounds emitted from the LRAD can be reflected back to the source by using a flat solid object.

If I had the time, I'd just go out to Chitown and set up a streetside booth with bottled water and earplugs for sale. Betcha someone reading this does just that. As for "flat, solid object", how about a nice sign that says "Can you hear me NOW??????"
heh.

What about ear-goggles/LRA D (shooting range)
and eye-goggles/pep per spray (scuba diving)

Imagine the Chicago Political structure not using it's new toy on the people. Who is the finest product of that political machine, Obama.Who will benefit from it's use Rom and Obama(remember the Chicago Cops represent a right wing Democratic Machine that delivers to the upper middle class.)"Brave New World".
