You couldn't really get guns in Plymouth when I was at school at least. There were a few incidents with illegal air rifles during some high-school gang stuff but nothing more serious than broken bones came out of it. When I was at college there was a day when the place was being inspected by Ofsted and someone had seen a man with a shotgun on the field and called the police...as the police turned up the fire alarm was set off and the students, school inspectors et al were evacuated just in time to see the riot police burst out of a couple of vans and try to apprehend this guy on the field. The excuse of the guy with the shotgun? He was trying to catch an escaped ferret. The police let him go.
