I'm seriously confused by what went down. First off, why are the police even reporting this? Secondly, what can the system even do? I'd believe a system could detect a person jaywalking. Identifying them is a huge problem though. running facial recognition against a billion person corpus seems impossible (in fact what even is your match data coming from?). (?). Wouldn't you need to narrow it down somehow, perhaps using phone GPS records?

chinese corp claims it can complete matching the whole population in 1 second but it's china so who knows what it's actually doing http://www.atimes.com/article/surveillance-system-can-scan-chinese-population-in-1-second/ http://www.atimes.com/article/surveillance-system-can-scan-c...

  Ya, I'm dubious there. accuracy rate "up to" 99.8%? What does "up to" mean? This article paints a much more realistic view of what face rec can do, which jives with my 10 year dated experience in this field: https://www.businessinsider.com/china-facial-recognition-limitations-2018-7 https://www.businessinsider.com/china-facial-recognition-lim... Impressive for sure, but nowhere at the ability of scanning the entire country (which in addition to no algorithm being capable of doing that, you also have the problem that you lack data to even match against the entire country)
