3. Read the whole story on Salon. It makes clear that there has been an effort to obscure the causes.

It also makes clear that the causes are real.

The declassified report even outlines one possible method of causing AHIs, using small devices that consist of "commercial off-the-shelf technology, use mature technology, are easily portable and concealable, and can be powered by standard electricity or batteries. Parametric acoustic arrays — also referred to as directional loudspeakers or acoustic lasers — are the most plausible technology, although other ultrasound technology may be at play."

No line of sight would be necessary, according to the report:

For radio frequency, no direct air pathway or line of sight is required. The strongest factors affecting the power received at a given location are the power transmitted, the antenna gain, the distance between the transmitter and the location, and what kinds of materials are in between. A number of different biological effects may occur, as a function of the frequencies and power densities on target. Any one specific transmitter type may have controllable power and variable pulsing.
