Hahahaha! I do that too! Guess I'm gunna have to stop now...
Seriously though, I would question their authority to photograph you with a speed camera when you weren't speeding... I doubt the photo could be used against you if it was obtained illegally...
Also, aren't speed cameras manned by rent-a-cops? Or is that only in southern states?
If they are going to charge you with "Giving an Obscene Gesture to a Police Officer", then it would have to be a police officer you gestured to...
Just my thoughts... I aint a lawyer though...
Show me the pic!
