Well? When I was a kid we heard of certain individuals who were so dangerous that they were bound by law to register their hands. When I would express doubt, a classmate would invariable claim that this was true because they knew someone who did this. Usually it was an older sister's boyfriend's uncle or some guy who was just far enough off the map so it couldn't be easily confirmed. But it would come up on TV programs from the 70's all the time. In an episode of the Partridge Family Lori tries to scare bullies away from Keith by telling them his hands were registered with the police. A friend's father owned a seedy bar that he called a night club and she told me her father said his bouncer's hands were registered with the police. So who has done this? Ever claim your hands were registered with the police to end a confrontation? How did it work out for you? Anyone know the origin of this? I can't really find a satisfying explanation other than it is some weird 70's folklore.
