The New York City Police Department has been sued for having allegedly injured demonstrators at a protest over the death of Eric Garner by using military-grade sound cannons to disperse them. According to a complaint filed on Thursday night against the NYPD and Commissioner William Bratton, five plaintiffs suffered ear damage and other injuries after being targeted at an early morning protest on Dec. 5, 2014 in midtown Manhattan by one of the NYPD's Long Range Acoustic Devices, or LRADs.
