Sonic weapons used in Iraq positioned at congressional townhall meetings in San Diego

"Long-range acoustic devices [LRADs] for crowd control can be extremely dangerous. These are used in Iraq to control insurgents. They can cause serious and lasting harm to humans…We want to know WHY our Sheriff Dept has this weapon," Sal Magallanez of San Diego-based Liberty One Radio said in an e-mail sent to East County Magazine, prompting a joint investigation. The device was stationed by San Diego County Sheriff deputies at a recent town hall forum hosted by Congresswoman Susan Davis (D-San Diego) in Spring Valley and at a subsequent town hall with Congressman Darrell Issa (R-San Diego). The Davis Rally drew an estimated 1,300-1,500 people, including vocal conservative and liberal protest groups. A public records search conducted by East County Magazine has confirmed that the device is an LRAD 500-x manufactured by San Diego-based American Technology Corporation (ATC). Capable of use as an effective loudspeaker, the LRAD also has the ability to emit a deafening tone aimed at incapacitating and dispersing a crowd without use of lethal force. read the rest here
