Due to the importance of the matter, here are my initial notes on helping find ways to measure and prove the problem of hidden energy beams aimed at people. Keep in mind, if you are surveilled building and setting up measurement systems, covert ultrasonic and electromagnetic weapons can be turned off as you attempt measurements, at the location of the measurement. My guess is the entire FCC is surveilled for this purpose.
Further, if you believe you have to keep the usage of ultrasonic and electromagnetic tactics, weapons, and control systems a secret, when they are commonly compromising private boundaries, properties, and law, then your secrecy model does not support democracy, rule of law, or American values. GTFO of my country and government if your festering within and propagating these beliefs to a free people.
