The appeal for sympathy the Sheriff makes claiming that police officers are the only group of people in the ENTIRE USA who care about protecting black people is incorrect.
Well, there are several ironies in his statements. But, first off is that he's Black. So, I doubt that he's saying Black lives don't matter when he criticizes "Black Lives Matter." That criticism is directed rightly at people who attack or kill police officers. If there is an organization with that name whose members target police officers, all that's really needed is infiltration --- by Black police officers!
It's part of the irony when he says "Blue Lives Matter" too. Obviously, if they're Black police officers, they believe their lives matter whether or not they have on their uniforms. Of course, the Blues Lives Matter quote got the whole audience standing. So, for the interested, and I'm sure that there'll be a youtube video with another pov, there's a reason why people find "Black Lives Matter" threatening, and needs to be countered with All Lives Matter; but, "Blue Lives Matter" receives a standing ovation.
Note how many people want to classify BLM as a hate and terrorist group; and then they compare it to the KKK, who've been selling White stuff for a century and a half. So, the actions or the avowed intent of the KKK and its members are equated to the acts and intents of whoever "belongs" to BLM --because people know what the KKK wants. However, the US is post-racial now, and one candidate was even asked to disavow support from the KKK. "Blue lives" is something everybody can go for without being racist, especially when spoken by a police officer. That Black lives would matter is terrifying to some.
Whoever argues that a police officer's life doesn't matter is a fool. That doesn't end with police officers, though. And, their lives don't matter because they're police officers. Nobody's life matters less, and there isn't anyone qualified to determine one way or the other, and no one is required to listen to that determination.
Anyway, again, black on black crime will be solved once white on white crime is solved, and then we can share the secret with the yellows, browns and others. It's also true that poor whites have a higher crime rate than rich ones. So, maybe economics might have something to do with it. Otoh, the crime rate among rich whites in America is astronomically higher than the rate of rich whites in Europe. (Hint, that last was just hyperbole). Then again, Italians and Irish areas used to be more crime ridden, just not street crime. I dunno. "White" seems such a limited concept. In the South, they used to argue that "mixed race" ("mongrel") people were the most crime prone. Watch "Birth of a Nation" (1915), not the one coming up about Nat Turner's Revolt.
