Classicly

But Duncan was always ready to forgive a Tarchik anything. That used to upset the hell out of them, too, because they expect to be punished when they're caught at anything. They don't understand our reluctance to kill, but they respect a Patrolman's shock gun, and when they get caught stealing or taking each other's tails they know they're going to get a few months in quod, or what they hate much worse, a public flogging. If they didn't get punished, they'd assume it was weakness on our part. Just like kids.
