Several people have posted how they use, or intend to use, pictures from GoPro or some other camera to have drivers ticketed or fined or whatever. I wonder just how that works. I understand that a cooperative PD that has time might talk to the "accused" based solely on the pictures. But, I'm not sure exactly how that goes on to a traffic ticket or a fine unless the cyclist is willing to file a formal complaint and, if contested, appear in whatever level court is involved.

So, mechanically what has been the experience of those who have actually done this, turned images over to the justice system for punitive action?
