IANAL but I'm curious about court challenges for these facial recognition apps/systems used by law enforcement. I knew of a guy years ago that caught a DUI based on a breathalyzer. His lawyer challenged the case and got it dismissed because the breathalyzer machine wasn't properly maintained, something about testing certifications. So, is a lawyer gonna be able to challenge these facial recognition systems, and get cases dismissed because of a failed unit test? Half-joking, but I look forward to these types of challenges.
The difference is that breathalyzers need to be regularly calibrated, otherwise they give wrong readings. There's no calibration needed for these systems once setup. And if they are wrong, the police will catch the wrong guy and end up leaving him once confirming his ID. I'm not that is not a problem, but it's not something that can be challenged in a court.
