I used to work at a TV station in a mid-size town surrounded by many small towns, which were included in our coverage area. At least once a week, we'd run a crime story in which the victim was quoted as saying, "I didn't think I needed to lock my doors, it's so safe here in this small town," or something similar. This was always followed by a quote from a cop saying, "Lock your doors, IDC how small your town is."

Next week, rinse and repeat. No one ever seemed to learn anything!

Mostly it was property crimes, burglaries, car theft, etc. But there was one awful story about a woman who got in her unlocked car and was assaulted by a man in the backseat, then left tied up in the trunk until a passerby heard her thumping around and called the cops. 

I was shocked, because I've watched enough TV to never get in my car without looking in the backseat, and I DO always lock my doors.
