First, I'd suggest you read
BadTux's
piece on what the cops call "black dog runs".
Second, one thing I keep thinking of is that, back during the debate on Obamacare, one would see no shortage of posts from Wingnuts, along with protests, promising "Second Amendment Solutions" and crap along the lines of watering the tree of freedom with blood. Some rancher grazes his cows on Federal land, the Feds get upset, and before you know it, busloads of angry old white dudes are out there with rifles, pointing them at the cops. Same sort of folks, promising revolution and so on and so forth.

But then you have places where the oppression of the population by the cops is not theoretical or a construct of the minds of those who put tinfoil linings in their ballcaps. The harassment and abuse of people who are guilty of no more than going about their business with skin darker than a sheet of cheap typing paper, harassment that takes place in city after city, need hardly be related here. One need only reflect on the fact that when police forces act so far outside of the law that the Department of Justice steps in and consent decrees result, those are almost never brought about by the cops abusing white folk.
The Baltimore cops killed a man whose sole crime was not wanting to talk to them. They denied him medical attention, then they not only tuned him up a little in the back of a paddy wagon, they crushed his larynx and snapped his spine.
And people aren't happy with
being beaten by the cops and yes, they don't believe that they'll get a fair shake from the justice system. Because they don't. When the cops don't act according to the rule of law, only a fool would expect that the people on the other side of the batons, the tasers, and the guns will respect the rule of law. Too many people, including cops, seem to confuse the meaning of the words "respect" and "fear".
Stopping a guy from grazing cows merits an armed response. Murdering a man in the back of a paddy wagon doesn't, at least, if one pays any heed to the Right on this. The former is a response to oppression. The latter is criminal action, if you buy their line.
Yes, a lot of what goes on in any riot is opportunism and hooliganism. Yet, one should not lose sight of how well the ground was prepared for it.
