I nodded. "Quite so. And yes, it is overkill." I was wondering if this defiant little bitch might be the next to go over the wall. That needed to be stopped. I decided to draw on a cliché to make the point. "I'm sure you've heard the expression 'using a sledgehammer to crack a nut'. The normal method of cracking a nut is with a nutcracker, yes? If you hit a nut with a sledge hammer, it cracks the nut, certainly, but... there is not really much left of the nut, is there? So tell me, under what circumstances would it be correct to use a sledgehammer to crack a nut? I can think of only one, personally."
