What does skin color have to with this? That seems like reckless alarmism. Humans are in the loop to validate facial recognition matches. It’s a first pass filter.
Ring cameras aren’t grainy. These are new, 1080p cameras, many with night vision capability. And again, if a human is in the loop then you are talking about a problem that is orthogonal to cameras - would a police officer jump to conclusions based on a poor, grainy match on non-IoT cameras or on photographs? Maybe on rare occasion, but the vast majority of the time, they wouldn’t.
