So...if you had a camera on your bike, and the bike got lifted, then what? Run down and confront a thief, who is presumably armed with a large heavy cutting tool?? Be out both a bike AND a web camera?

At work, folks park in a garage with video surveillance. A woman actually had pictures from those cameras of her bike being stolen and ridden out of the garage that she presented to police. They still couldn't/didn't do anything about it.
