It's possible this could be fought by building a fairly large corner-cube retroreflector and aiming it at the source of the sound. While that might not be precise, it would send a lot of sound back to the area around the emitter. Jim Bell

LRADS can be defeated with earbuds and metal music. Just read the police in Hawaii used one to break up a native protest at a burial ground due for condo development. The organizer clarified that the LRAD was used like a super-loud bullhorn. Not as a weapon. I suspect they're pretty much useless as a crowd control tool if the crowd is prepared. Next up... Subsonic weapons. The band Devo had the right idea when they suggested they were going to do a show with hyped-up subsonics, hand out diapers at the door, and make the concertgoers shit their britches. IMAGINE the demoralizing effect on protesters with their pants full. Rr Sent from my Androgyne dee-vice with K-9 Mail
