Kind of divided on this one because it could go ether way, bad for the individual like you say Suntzu, or it could help the person in proving innocence. It is all in the way the video or other information about the person is presented to the public.
The video of the guy robbing the bank, or those recently in my area showed two guys in a store after hours stealing everything that wasn't nailed down. They even damaged one of those cameras so they could not be seen. They didn't get the hidden one and the video provided by the store owner helped capture the thugs.
I understand what you are saying, but unless there is a law that does not permit featuring video, then we will most likely continue to see it happen. No definitive answer unless some guidelines are in place on how to handle this kind of thing.
