AERIAL SURVEILLANCE HARASSMENT (part of the targeted individuals program), by using small planes and using helicopters to follow individual. This was on 07/27/2020 on N Schuyler. The black helicopter I couldn’t get a picture of as I was pulling into the bourbonnais post office on 07/28/2020around 5:15ish. The point is to fly over and around the targeted individual to make them seem crazy if they tell o th era. They use mental illness as a weapon.
