What America needs to do is change the cultural feelings towards police of our poor minorities. Whether the absolute number of folks killed by police changes at all is irrelevant.
LOL.
It's an onion and you're now addressing something like the 18th result of the base problem.
Many black people have no respect for police because they are convinced that the police accost them for "no reason". The police give special attention to black people because the majority of violent crimes are done by young black males (and other, non-violent crimes have a disproportionate representation of black people committing them, as well.)
Black youth commit crimes because their culture glorifies criminality. Their culture glorifies criminality because there are few or no male authority figures within the life of black youth. Black male authority figures are absent because the black nuclear family was nuked (see what I did there?) in the 1960s. The black nuclear family was nuked because (1) Great Society rewarded women for having children out of wedlock with more benefits and (2) the concurrent Sexual Revolution convinced too many that sex is as meaningless as taking a walk in the park, and ought to be engaged in as often as possible with no concern for the consequences.
These, of course, were successful because Christian morals were denigrated as backwards and out of touch and part of what was holding humanity back. (Especially the sex part.)
So, ultimately, the only way to get respect for police officers is to replace the lost morality in this country. (It needs to be replaced with something that encourages hard work, thrift, and delayed gratification. If only there were some... philosophy or teachings of some kind.... that did that.)
Note, the white underclass, though proportionally smaller, suffers the exact same malaise and the solutions are the same.
Of course, I'm just a social conservative and, therefore, satan incarnate to the Democrats and the "fiscal conservatives".
