"National Lawyers Guild Challenges NYPD on Use of Sound Cannons Against Peaceful Protesters"
"The New York Police Department is being challenged by legal advocates for what they say was the department's use of untested, unregulated military-grade sound cannons during civil rights marches in Manhattan earlier this month.
In a letter (pdf) sent to the office of Police Commissioner Bill Bratton on Friday, the National Lawyers Guild said the department's use of long range acoustic devices (LRADs) against peaceful street protesters violated numerous constitutional amendments. The group demanded a safety review of the device and public release of guidelines over how and under what circumstances they could be deployed.
Videos of officers using the LRADs surfaced on December 4 and 5 during marches that came after a grand jury's failure to indict NYPD officer Daniel Pantaleo for the chokehold death of Eric Garner. Crowds can be seen dispersing quickly as loud, shrill, repetitive beeps ring out in short blasts over and over."
