I read your initial post as kidding, and read the replies as things we wished we could do in that situation but wouldn't for the very fact that it *is* illegal. A little revenge fantasy is a pretty good way to blow off steam in my opinion, especially when already dealing with the frustration of a dead battery...
While the replies were sounding semi-serious, I don't think anyone was actually advocating or even remotely suggesting he actually do it. :)
