I walk past two sets of facial scanners on my way to and from work. Huge numbers of people are scanned, I doubt anywhere near 1% of the public is "wanted" so false positives will massively out weight true positives. Ironically there are quite a few young people with their faces covered often with skull masks etc, I've never seen them stopped. I'm sure they do it to seem cool. The cameras are in the same place all the time. It seems somewhat baffling but I suppose it's to deter (or intimidate) people than actually catch many.
