A man-portable non-lethal pressure shield provides both a physical as well as pressure shield. The pressure shield addresses the concerns of military, police and human rights organizations and international law as regards effectiveness, efficiency and safety and efficiency. A folded acoustic horn is incorporated into the physical shell of the shield. The horn couples acoustic pulses from a sonic pulse generator to an acoustic aperture to output a pulsed pressure beam that approximates a plane wave to produce a pressure barrier. The operator may specify a desired effect on its human target that is maintained as range-to-target changes or a desired effect at a specified perimeter range. The shields may be networked to facilitate coordinated action among multiple pressure shields as a force multiplier or to provide a more sophisticated pressure

    Can you imagine the mind-set of the people responsible for supporting this kind of use of tax paid money? We haven’t see this kind of thinking since the days of a Nazi run government. Why are we allowing this?

    This is a laughable waste of money as rubber bullets, baton rounds, fire hoses on low pressure, tasers, existing riot shields and kevlar vests are an already-created, very dependable and far more cost effective deterrent, not to mention that they will not cause deafness as these devices will. And if these devices are meant to silence protesters, or reinforce police brutality, that brings the perversion of this idea to a new level.
