I do this for a very simple reason. I don’t want to be robbed. It doesn’t mean I think robbery is “okay” when done against people stupid enough to leave their doors unlocked. It doesn’t mean I think most people are robbers. Most people, in fact, are honest. It is the dishonest few that concern me. Nor do I think that my actions are a guarantee against being robbed. It just makes my home less attractive to robbers. Furthermore, if you leave your door standing wide open, and you get robbed, the police will criticize you for having left your door standing wide open. This does not mean that they support a “robbery culture.” It doesn’t mean they think the robbery was okay. It means they think that your sheer stupidity has made more work for them.
