Why is gun control bad?

It's bad because if the teachers start raping and killing the students they have something to defend themselves with.

so... that means that if a person was determined to get such a weapon they could. Got it.

What a terrible analogy. It should be
>A violent kid on the playground is standing on a mountain of rocks and has no respect for authority and won't talk. How do we get him off of the mountain of rocks if we do it non-violently?
