But sadly a large number of black men are unable to legally exercise this right due to lifetime loss of rights for any felony conviction or domestic violence misdemeanor conviction. Why black men have such a higher rate of felony convictions than do white men (a black man is about 8x more likely to commit/be convicted of murder than is a white man) is a subject way off topic for this board.
But to the extent that there is a problem with police using excessive force, I wonder to what extent it is actually racially based, vs socially economically based. Last year here in Utah some under-cover, out-of-uniform cops shot a young woman dead as she backed out of parking spot in her car after she didn't obey their orders to stop. They claim they identified themselves as cops, but they weren't dressed as cops. They claimed they were in fear for their lives from her "trying to run over" one officer. The shooting was ruled unjustified and one of the cops was brought up on charges, but the judge tossed the case at the preliminary hearing. The shooting brought to light a whole host of problems in that particular unit and department including gross mishandling of evidence that resulted in charges being dropped in dozens of cases. Everyone involved was white. Entirely coincidentally, I'm sure, I don't recall the case getting much national press nor attention from civil rights groups other than just locally.
It seems a poor, white, low-level (former?) drug user who gets shot dead by cops while backing out of a parking stall is just a statistic, while large, violent, black men who assault cops and try to take their guns are cause celebre.
I'm worried about excessive force from cops. I'm no less worried about how the media stokes the flames of racial discord in this nation.
