What you are talking about are more crimes of opportunity. The best thing is to have items you can easily take with you. Unfortunately you never know what a thief is thinking or what they will take. I once had some thief steal an empty saddle bag which was not in the best of conditions.
One of the reasons I don't use panniers is that I wouldn't feel safe if I left them on the bike. I have a rear rack with a milk crate attached and throw my back pack in it while riding.
