buggering car thieves....its a good idea but its alot less risky to just get them convicted and let someone else do the buggering while they're locked up. this system is already in place after all and it avoids any gangs of car thieves coming round your house to get revenge. (keeping with the pulp fiction theme - remember what happened to Zed !)
cutting fingers and ultimately hands off is the way to stop thieving, it works in the middle east (most of time!)
addition : -i would be keen to apply for the position of "finger cutter off'er" should this happen...ok just sayin
