It sounds broken from an regular perspective, because regular people either don't get involved in thinking very hard about crime and probabilities, or if they do, they get a gun or some other form of protection to put themselves more at ease. Thinking about crime happning right at this moment, in your very own neighbourhood all day, but feeling like you're an ineffectual shut-in nerd who wouldn't even be able to use a gun if his caring mother would let him have one, would drive anyone to paranoia, I think—myself included.
