For a Non-Lethal Weapon, Israel Uses Sound

Two weeks ago, the Israeli Army used a new weapon dubbed "The Scream" to disperse a demonstration in the West Bank. It's a non-lethal weapon that sends out bursts of sound.

Malcolm Davies studies non-lethal weapons at the British Joint Services Command Staff College. Davies says the sound creates vibrations in the organs, which cause nausea and dizziness. He sees "the Scream" as more effective than weapons such as rubber bullets and tear gas.
