This entire thread is people taking my analogy and shooting in the face. The point is this: jut because a crime is trivial and likely to happen doesn't mean we shouldn't blame the criminal. Yes, you're an idiot if you leave the keys in the ignition of your expensive car and you're even more of an idiot if you're surprised your car got stolen. But that doesn't make stealing it any less of a crime or the criminal any less responsible.
