Nonlethal weapons such as high-power microwave devices should be used on American citizens in crowd-control situations before being used on the battlefield, the Air Force secretary said Tuesday. The object is basically public relations. Domestic use would make it easier to avoid questions from others about possible safety considerations, said Secretary Michael Wynne. If we're not willing to use it here against our fellow citizens, then we should not be willing to use it in a wartime situation," said Wynne. Nonlethal weapons generally can weaken people if they are hit with the beam. Some of the weapons can emit short, intense energy pulses that also can be effective in disabling some electronic devices.
