I doubt the wardens provide anyone with them. But in a prison where we're free to do as we please, wouldn't some people have made themselves some kind of weapon by now? This place is supposed to be filled with "dangerous criminals", after all. [How else would you defend yourself from them?
And to be fair he's thinking the kind of weapons you can make a rudimentary version of yourself in a pinch, not machine guns.]
