Where is the highest probability of homicide/murders likely to be committed.

You open a loophole and the criminal mind will be through before you can blink.

Look what Hitler got away with, until it was too late - the cost was 50 million lives. His was a criminal mind and the world 'appeased' him for too long - an extreme example, but it happens if you let it.
