The card reads "If I were a criminal I could have..."

Then police officer will fill out the rest of the information telling the cars owner what could have been stolen and to remind them to lock their doors.

This practice occurs in nearby Dixon, and while some have taken issue with police entering a car just to prove a point, I think it's a pretty classy thing to do.

The thing that I can't understand, (and I'm sure I never will) is who leaves their car doors unlocked? I don't care where you live, you lock your doors.
