The number is really low no matter what source you try to use...now, you’ll try to say that black people are disproportionately killed by cops which may be slightly true...however, blacks make up 13% of the population yet they account for over 50% of all violent crimes in this country which means that law enforcement has to devote more time & resources to black communities than any other community in this country. So naturally, given that you’re approximately 4 more times likely to be the victim of a violent crime in a black community (cops included), it’s just common sense that there will be more citizen/cop conflict in those stressful communities...
I know this is over some of your heads, but it’s not really that hard to understand if you attempt to take your politics out of it.
