That does not remove the logical fallacy of implying that because police are (wrongly, as you say) a mortal threat to those who resist arrests, therefore police are one of the biggest threats (if not the threat) in an average black persons life. The recent two cases do not offer convincing evidence for the latter (although other cases may do so).
Of course this (particular topic) isn't really a place for arguing for an argument's sake. Rather, it's for showing your compassion.
I think you're correct. They're likely not the biggest threat. That's probably heart disease, cancer, or diabetes in the US. Violence of any kind is way down the list for most people.
I don't think they have to be the biggest threat to acknowledge that the police are out of control and above the law. Fix them, or abolish them and recreate them if they can't be fixed.
This issue goes well beyond racism. Blacks feel it the most, but this problem affects everybody. Nobody wants police that can steal from you (civil forfeiture) or assault or even kill you without sufficient reason or consequences.
Yes, the world is not perfect in many ways.
