I’d be in favor of banning facial recognition as evidence used in trials, but still allowing it to aid in investigations. I.e let it help narrow down suspects when faced with grainy footage, but can’t be used to actually make a conviction.
Seems way too easy to abuse. At least in the US, police already use junk science to "place" people near the scene of a crime, and then prosecutors use circumstantial evidence to get convictions. Or worse yet, police will, in the US, probably use this to get plea deals. I guess many EU countries don't have plea bargains through?
