I don't get it though. False matches seem to be a great thing: it means that facial recognition does not really work well and can't be used to tell who is where. Do you prefer FR that never makes mistakes?
Adding more tools we know will be abused at a time like this seems like adding fuel to fire and removing accountability from individual actions.
You might have a better chance fighting a case where you are stopped for no reason than fighting a case where your car is pulled over because the FR system mistook your blurry face for that of someone else due to poor lighting.
The fact is that you're not trying to put out the fire (I am talking about the US, as this seems to be first and foremost a US issue). You're actually feeding it, in the conviction that it's the right thing to do. Removing the worst flammable materials is pretty pointless when you have already decided that you want the fire to keep burning because you still think it's for the best.
Out of the metaphor, the US police seems to be uniquely prone to escalating conflicts and generally asserting its absolute power because it's expression of the law. From the outside, the US seem to be a society where everyone (starting from the police, down to citizens, criminals, law enforcement and prisons) is encouraged to "stand their ground" up to the highest possible level of conflict, without a space for mediation, forgiveness or oblivion. That is the fire, and the US thinks it's just fine to keep it burning.
