How many? Because apparently we haven't yet reached it with body cams.
Like I know?
But if you compound different systems, like the ai handgun thing and dont store the data in the same place, it becomes exponentially less likely that suddenly 2 critical systems failed at the same important moment for some reason.
the real issue with police brutality is the fact that it is, in fact, legal, and police is trained to respond in such a way. what protesters get wrong about police brutality is that its supposedly illegal. it is not. most instances of police killing someone are actually legal. which doesn't make it right. but its legal. saying somethings illegal when its not just makes you look like an idiot.
people need to protest for better laws, not getting individual cops sentenced, because that wont ever happen with any kind of regularity.
I imagine that, like body cameras, the AI thing will, in those events, conveniently be deactivated, malfunctioning, misplaced, or have it's records lost.
