It's interesting that they don't mention how/if they're avoiding false positives. I don't doubt that some people have exceptional facial recognition skills, but if they're given a face they haven't seen before, how likely are they to match that face with someone they have seen? How do they know that someone wearing a mask on a security camera is enough information for him to actually make an accurate match?

I'm worried this might be another case of police over estimating how effective something is (like hair DNA forensics) to make arrests, with innocent people paying for it.
