People need to remember-- when you are the one being "hassled" that is probably because someone else is being protected. Public Safety doesn't get a bonus for busting people, they respond when other people have lodged noise complaints or claimed that they don't feel safe. Just remember how much you have bitched next time you're the one who needs help. Sure, it's annoying to be the one who is confronted when you don't think you deserve it, but that is someone else's need to feel safe.
People who complain about security also tend to be the first ones who complain when they feel like they are not adequately protected.
