Long Range Acoustic Device to Be Deployed in Chicago NATO Protests

By Paul Meincke, ABC7 Chicago 13 April 12

Chicago 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.
