What?! First of all, if someone is in the military, how in the hell are they going to "DO" A school shooting? They're freaking adults! Secondly, the song speaks to soldiers on a level that most people can't even begin to try to understand because they've never been in a situation that dictates making the choice between taking a life or allowing your own to be taken. Clearly, the lines "you can all hide behind your desks now" and "you can cry 'teacher come help me'" describe the common mentality of soldiers that civilians can sleep in peace in their sheltered world because they are on the frontlines keeping the wolves at bay. It doesn't promote school violence, it doesn't promote "using violence to get what they want". It is simply an homage to the thousands that get so little thanks for doing the terrible job that no one else wants.
