The store clerk (who hadn't witnessed the crime and was going off the same frame of video fed into the facial recognition software) said the driver's license photo was a match.
There are several problems with the conduct of the police in this story but IMHO the use of facial recognition is not the most egregious.
Our institutions and systems (and maybe humans in general) are not robust enough to cleanly handle these powers, and we are making the same mistake over and over and over again.
The mistake is to treat any police department as a good-faith participant in the goal of reducing police violence. Any tool you give them will be used to brutalize. The only solution is to give them less.
