99% accurate would still lead to a huge number of false positives because most people aren't criminals. The base rate of non-criminals is so much larger than the number of criminals that there would be hundreds of thousands or millions of false positives, depending on how widely facial recognition was deployed. There would be many times more false positives than accurate identifications.

If you have a population of 100M, even if 1M match, then you add geographic area, skin colour, hair colour/style, height, known criminality, ... suddenly you're down to enough people you can investigate. Sure, if your police/justice system is not competent you have a problem, but you had that in the first place.
