Unfortunately it seems they will use the facial recognition excuse to jail and imprison the wrong people just like they did before the advent of facial recognition. It is simply an imperfect tool, and in the wrong hands a blunt instrument of punishment of the innocent. The recent example from New Jersey of a clearly innocent person being "framed" by the facial recognition excuse:

Parks claimed that as he sat in jail for 10 days, police and prosecutors didn't bother to check fingerprints and DNA at the scene that could have cleared him.

"Defendant police department was relying solely on the faulty and illegal [facial recognition software] or some analogous program while all evidence and forensics confirmed plaintiff had no relationship to the suspect for the crimes," according to Sexton.
