You missed one: Nowhere are people lives more imperiled by police's direct aggressiveness. And given the numerous examples we've seen over the years, and the many, many black people who have been saying this for decades, it really shouldn't have ever been overlooked.
(Also, stats on police behavior against Native Americans, and people with mental health issues, show all of the above to be false, but put that aside).
The Charles Stuart case was considered a relative low in Boston, compared to the 60s and 70s when police would routinely just run up and beat the hell out of a black guy, and then leave - not to mention that they routinely showed up in white supremacist rallies, as the white supremacists. In far too many areas, the absolute first step is for police to realize that they've spent their entire organizational history going out of their way to earn the distrust that they have, and then reorganize themselves from there so as to correct the problem that they've always fed into.
It's worth noting that the National black police unions have almost entirely agreed with Kaepernick, even as the general unionists scream at how awful he is. That should tell you something right there.
