The Israeli army’s using a low-frequency sound gun to break up crowds. Though you can’t hear it, it’s set at a frequency that affects your inner ear — making you feel nauseous and dizzy. Apparently it does wonders to break up thronging crowds of angry Palestinians. Although the use of force is not nice, a sound gun seems a lot less violent than clubs, stun guns, and other weapons.Imagine having a pocket version of the sound gun — you could break up a crowd anytime you felt like it! At the club, in a restaurant, in the grocery store line… the possibilities are endless.
