There's far more than the racial component. Do you want the government tracking you? It helps authoritarian rule (who always victimize minorities first and more harshly). I think a big problem with this topic is that we're only focusing on the "it doesn't work" aspect and not even considering the "but what if it perfectly works, do we still want it?" question. Humans haven't historically been great at dealing with questions that rely on foresight, but that doesn't mean we should ignore those questions.
Exactly. No one wants to live in a word where 100% of crimes are prosecuted 100% of the time. Not really.
Do you want to receive a citation every time you exceed the speed limit by 1 mph? Ever pull off into a parking lot to check your phone or look for something in your car? Trespassing. Ever lose your temper and yell at someone, even briefly? That's assault in most jurisdictions.
