There's several key points missing in your second paragraph that are pretty pervasive and systemic. In Ferguson, MO for instance, a higher percentage of the black population had a record, tickets, run ins with the law? Why? Were they as a people different? IIRC the review done there indicated that more enforcement was sent there, more tickets issued there, more people were stopped there. So naturally the incidence of people getting charged, ticketed, etc will be higher. If the same level of enforcement was targeted and applied in the white areas with no biases, I bet the outcome would be the same. For instance when I lived in Dallas, I knew people that got pulled over/harassed all the time because of the neighborhood they were in. But I had friends that could literally smoke a joint in front of the cops in the "good part of town" and get waved at. Different areas, different enforcement, different outcomes, and different permanent records.
As far the LEO's having a hard job --- there's lot of hard jobs out there. On the other hand, there's not a lot of hard jobs where people can kill other humans and likely walk and be protected by unions, QI and public perception being on their side. Again, hard job, but a high standard to bear. We could go back to the question "how can we make the job easier?" That could get into the "defund the police" argument. Like, seriously, why not have trained people go respond to mental health calls? I'm personally sick and tired of autistic people getting shot by cops for instance. Why not have social workers go deal with homeless folks? What else --- maybe instead of needing to take someone in RIGHT NOW and "tazing" them to death with a bullet, we look at capturing under better circumstances? Tail them, wait for backup, etc.
Are those perfect answers? No. I'm not an authority on the figure, but just a dude thinking of ways that might be better than what we've got. But until the bootlickers realize that the feet inside those are connected to real humans rather than perfect gods, things won't change. What will change is that eventually the protests against violence (that are met usually with extraordinary violence), will descend into war soon enough if things don't actually start changing.
That's the reason I used arrests for violent crimes, not petty crimes and tickets. I've seen some evidence that the 'driving while black' thing happens. I don't think it's as pervasive or necessarily as simple as depicted though. Context matters. I suppose you could still argue that blacks are arrested for violent crimes in instances where whites would not have been. But I don't think that's the case on any significant basis.
I'm softening on QI somewhat. I don't think it should be wiped out and allow individual cops to be sued. Maybe the the employer, in certain instances. There has to be a valve of some type in place or this could turn into a ridiculous farce of lawsuits and waste of resources.
I assume your "tazing them to death with a bullet" refers to Daunte Wright. This is an example of what I was talking about. Perfect judgment and execution demanded in a split second. Based on the video, I don't believe anyone that says more than a mistake was made is being honest. Or they are are SO biased they are blind. Should ALL resistance result in immediate stand down unless the cop is in immediate peril? Do you see that as workable? Do you think it would take 5 seconds before every arrest involved resistance? Hypothetically, what would have happened if Daunte was allowed to take off in his car, but then hit a tree, ejecting and killing his girlfriend. Would the family's attorney sue? Would they win, since the cop had the opportunity to prevent it?
So someone calls 911 because of a mental health crisis and you want to send, I assume, unarmed social workers to handle it? I'm going to pass on that job.
