Example use of short range mind invasive/electronic harassment devices used by the police on mass crowds. The LRAD's were set to cause pain in their bodies and people heard the loud noise in the background (hear the sirens?).
LRAD is short for Long Range Acoustic Device.
Other versions work from space and use microwaves or other frequencies and can cause pain, sound, alter brain function, heat and chill a person, massage and kill (by inducing calcium efflux), and do environmental things including messing with electronics.
They have long range tomography that does brain and body scans, works through buildings and even scans through ground. There is not a place you can escape from it. They call it interferometry.
