I imagine false positives would be handled by human agents looking at the photograph, then looking at the person's face in real life, and perhaps talking to them.
If you're lucky, you won't spend more than the weekend in jail before they correct their mistake.
Now I for one do not have a problem with them using public surveillance or Driver's License ID's. If you go out in Public, you consent to being watched by the same public and by extension, the Government. It is completely acceptable and good for them to use this legally obtained data in an automated recongnition system. Yes there needs to be checks and balances but the problem doesn lie in the source of the images.
You might not, but there are lots of us that do mind being tracked. There are lots of people in jail because the police add 2 + 2 and get 5.
When the Nazis came for the communists,
I remained silent;
I was not a communist.
When they locked up the social democrats,
I remained silent;
I was not a social democrat.
When they came for the trade unionists,
I did not speak out;
I was not a trade unionist.
When they came for the Jews,
I remained silent;
I wasn't a Jew.
When they came for me,
there was no one left to speak out.
