I don't know - there's alot of crazy teachers too.
The sex abuse crisis in the schools is much worse than it ever was in the catholic church...do we want to read about kids getting coerced into sex at gunpoint?
Besides - a majority of teachers are lefties...the sight of a gun frightens them. I don't want them trying to handle guns around my kids. I'm guessing my kids would do a better job in that regard.
