"Street theater" when spoken of in a gang stalking context refers to carefully scripted harassment by neighbors and strangers especially, but can include harassment by family, friends and co-workers. These skits are designed to keep a target at a high stress level, but are crafted so that outside observers are likely to wave the skits off as "the breaks". The cumulative effect of such skits can be crushing to sensitive victims. Noise, crowding in person or on the highway, stealing items from shopping cart when in the checkout line, and kids sent to hang out in front of, stare, make noise, in front of a victim's house or by putting strange items on a lawn as the victim drives by, such as a vacuum cleaner!
Because it is common to get out of cars it is hard for other people to understand. However in Gang Stalking this is shown to the victim in an overt way at first in a very unusual manner. In the example above it is obvious only to the victim that the person is sitting in the car waiting to get out as the victim goes by, instead of pulling up, stopping and getting out in a normal sequence.
