The American Civil Liberties Union of Pennsylvania filed a federal lawsuit today on behalf of Karen Piper, a bystander who suffered permanent hearing loss after Pittsburgh police deployed a Long Range Acoustic Device (LRAD) against protestors during the 2009 G-20 Summit. An LRAD emits harmful, pain-inducing sounds over long distances. Developed for use by the military, LRAD technology had never before been used against US civilians….
Piper immediately suffered intense pain as mucus discharged from her ear. She became nauseous and dizzy and developed a severe headache. Since then, Piper has suffered from tinnitus (ringing of the ears), barotrauma, left ear pain and fluid drainage, dizziness, and nausea. She still suffers from permanent nerve damage.
