Gestapo USA

My high school was surrounded by one way back in 2002, although it wasn't a chain link one. It was made of metal bars, maybe 2 inches in diameter and 15 feet high. There was a large enough inside area on one side to safely get away from the building if there was a fire, though. It was mainly to prevent kids from leaving the campus during the day. Otherwise a lot of kids would just walk off campus to skip. Although, that really wasn't effective anyway. Kids could also easily skip classes behind the bleachers in the gym. There was also a science teacher that had completely checked out and would let kids smoke weed and do hallucinogens in his classroom while he just sat at his desk doing nothing. Any kids could go to his classroom to skip the ones they were supposed to be in.
