Disapproving reporter: 1, castle: 0, teacher: 0. I'm filing this one as another case of, "I'm actually quite surprised they didn't arrest the property owner for assault."
Were it Texas, the property would've survived unscathed, but I wouldn't place the teacher's chances anywhere near as high, both on the "surviving" and "unscathed" odds.
I'm not completely sure that's a good thing. It really would be a shame if some damned fool got drunk and ended up dead because of a set of really idiotic actions. After all, that damned fool could be me! Then again, being an American and quite aware of the potential consequences of playing this particular game in the US, perhaps I'd be less likely to do something quite so spectacularly dumb. Deterrence at its finest!
