Exactly, and well put. I totally understand this from the cops' point of view. This issue is the basic unfairness to a person who simply happens to be black. To go back to Homer and I, we are both individuals; statistics about crime have nothing to do with us personally. Yet we will be treated differently when cops have to make instant life and death decisions. That is prejudice; we have both been pre-judged based solely on superficial things we can't change. (Also on superficial things we can change, such as clothing and tattoos, but it's the things we can't change that form the basis of society's unfairness.)
This isn't easily changed. One thing that will help is better training. Cops should get the same training as do soldiers and Marines preparing for peacekeeping duty deployment in hostile areas. This should be a periodic requirement too; people do change, skills do get lost. Another thing that should change is police recruiting. An absolute requirement of the job is the willingness to run toward the shooting rather than away. But that isn't the only requirement; there is also a need for restraint, so that after running toward the shooting, the cop doesn't shoot the wrong people. Or for that matter, anyone who doesn't absolutely have to be shot. To effectively do their jobs, police officers are entrusted with deadly force and the presumption (barring evidence to the contrary) of being justified in using it. That is a huge amount of power, and both selection, training, and ongoing monitoring are critical.
I think another thing that would help a huge amount is to get cops out of the cars and onto the sidewalks. Cops cruising by in a black area see only a sea of faces, most (to them) hostile. Same thing with the way the locals see the cops. Get them on foot, talking to the people, interacting with the people, they see them as individuals. This one is hostile, that one is friendly. This one is on drugs, that one is working two jobs and raising his grandchild. This one hates cops and is likely dangerous - but that one over there is his cousin and can talk him down. When you get to know people, even superficially, it's harder to think in terms of us and them rather than as individuals. That applies to both sides equally. When you don't know the cops but you do know the guy they shot, it's harder to admit that it might have been justified.
I call bullshit on your bullshit. Even where no one is arrested, race is often known. The most common victims of black violence are other black people, and it's just silly to argue that a dozen black people shot/shot at stereotyped a car of white guys committing a drive-by shooting into a car of black guys. Same with home invasions, carjackings, armed robbery, etc.
I completely agree that it's unjust to judge black people on the base of racial statistics. Groups don't commit crimes, individuals do, and individuals are not necessarily in any way similar to people they superficially resemble any more than guys who look like Bernie Madoff are necessarily scam artists looking to steal your life savings. I just don't see how to fix it as long as the underlying statistics don't change. We can however lessen it, with better cops and especially with better training and practices.
More black cops would also probably help. Even black cops assume black men are more likely to be threats than are men of other races. But if an officer (of any race) is riding a squad car every day with a black officer, that has to make him less likely to pre-judge a particular black man as threatening based solely on race.
