content: If you're arguing that they're justified in calling the cops, then you're surely in agreement that they were negligent in not evacuating the school and calling the bomb squad. You don't call the cops to discipline a student--the only situation in which the cops are required is one in which you believe there's actually a bomb. If they were sure it wasn't a bomb they should've just taken whatever disciplinary action was appropriate, such as a detention for repeatedly interrupting class. We shouldn't be encouraging anyone to call the cops for what's obviously not a bomb, just as they shouldn't treat kids like criminals for playing cops and robbers or biting poptarts into "the shape of a gun." Zero tolerance is retarded and should be resisted.
