Lock me up!

Every now and then, our university has problems with thieves getting inside the campus. And it doesn't help the situation when students leave their things on benches or leave their cars unlocked. The latter got so bad two years ago that our security guards were spending more time checking for unlocked cars than guarding against strangers (i.e., no IDs). Yes, we all know that it shouldn't be the responsibility of the school to play babysitter for careless students, but it does become the school's problem when things get stolen inside the campus. So at the start of the past school year, the university put up reminder banners in all of the parking lots, and this simple and inexpensive solution actually helped. The incidence of unlocked cars dropped dramatically and I don't remember reading a single report about car stereos or laptops left inside cars getting stolen. I think it helped that the cartoon car looks so cute and worried. How can you neglect the safety of your pet car when he's looking at you like that?
