make the punishment fit the crime

yesterday my six year old son was telling me what to do if a bully smashes up your snowman. next time, build your snowman around a postbox. when the bully kicks the snowman he breaks his foot. excellent.

which got me thinking. why not design robot boys and girls to wander about so that when gary glitter and his ilk put their dicks or fingers in they get electrocuted. and leave cars lying about which explode when people steal them. etc etc. but i suppose it would be entrapment or something.

it's probably something i read in 2000AD back in the seventies, coming back to me as an original thought, like what simon was talking about.
