Pittsburgh Police Use Sonic Weapons Against Protesters

Pittsburgh police, over in the land of the free and the home of the burst ear drum, have shown once again their interpretation of the meaning of 'a proportionate response' by using military grade 'sonic weapons' against their own citizens during protests against the G20 summit.

This technology has previously been deployed against Somali pirates and Iraqi insurgents - and by the Israeli army against Palestinians. Noise at frequencies used by this kind of weapon affects the inner ear, creating dizziness and nausea and can cause hearing damage.

WARNING: the sound of a sonic weapon is annoying even when it's 3725 miles away...
