bushbeater
Someone who searches wooded areas in local parks for homeless camps or other squatters,this may sometimes be the police, sometimes a resident from a nearby neighborhood, or occasionally another homeless person. Bushbeaters almost always do so with ill intent, either to force the squatters to move on, trash the camp, or to rob them of whatever is not nailed down.
