Upon special requests, I also sign autographs. Most recently when a state trooper asked me to sign my written statement regarding an incident, before he proceeded to hand me a ticket. I digress...
Good for that guy. In this technical age I don't get asked for my autograph as often by LEO. I have had several unauthorized photograph requests, in the form of red light cameras. I'm a very photogenic driver it turns out. And I'm hideous.
