I'm not sure I understand the problem of Jamie McClelland. I've just checked and I have three kinds of government-issued ID cards with my photo (passport, driving license, ID card), so the government has at least three databases where they could look up my name from a photo. It means that if their technology is as good as Facebook's, they can already track movements, etc. I think it's not legal to access these databases for a police investigation, but the tracking itself would be not legal either...

Face-recognition data works better with more data -- particularly with photos showing each subject in a number of different angles, lighting conditions, facial expressions, etc. So the authorities will have much better luck recognizing a photo from, say, a protest against Facebook's database than against the DMV's or the Passport Agency's.
