This is something I can more or less speak to having encountered a great many people who are at least partially criminals. It does not matter about all the cameras, employees, and security. Thieves always think they are smarter, better, different and think they will not get caught. And due to the limits of observation, proof, etc, most of the time they are right.

A harasser would no more stay away from Wiscon than Willie Sutton would stay away from a bank just because of one guard.
