All the criminals aren't black, but black males commit about 50% of the serious crimes in the US despite being only about 6% of the population.
I believe this stat is unchallenged, still widely accepted.
Couple more stats:
Blacks % in sports:
NFL...71%
NBA...73%
There is no doubt that blacks dominate in the U.S. two most violent sports requiring probably the most exertion with agility.
Possibly, before anyone commits a violent crime, they need the confidence that they can dominate almost anyone else in one on one combat.
Next biggest possible contributor is cultural radicalization.
Black on black crime is high partly because of the culture of respect. In such cultures, you dare not make extended eye contact, or even any at all. Or you dare not tell someone what to do. And any number of social minefields almost impossible to negotiate.
Also, the fact that 90% are culturally influenced by the Democrat party probably contributes to the 50% number.
The culture of music, and how it can get people focused on fronting an image which requires more fast cash than most young men are able to raise in a regular job...is also a factor.
Finally, black on white crime is high because of culturally reinforced racism, which is probably the fastest growing factor in the progress of cultural radicalization.
If you took all US blacks and exchanged them for African blacks from almost any primarily black African nation, that 50% number might actually go down to 6%-10% simply because the primary factors are cultural, and I think Denzel Washington has stated as much. Cultural rather than racial. African blacks are actually generally less racist against whites and have a less lethal music culture.
If blacks do have a racial (rather than cultural) tendency toward higher per capita violent crime, it could be for the same reason more men commit violent crime than women. It has something to do with testosterone and ego, factors that help blacks dominate in the top two violent sports.
Back in the sixties, Charles Manson was heavily influenced by a narrative of a war between blacks and whites...and got his group to follow him into the desert to look for a cave in which to hide while the war was fought. Crazy!
Today, it's the Democrat party stoking the fires of racism through it's identity politics...so crazy it makes Charles Manson look like a Boy Scout. I myself fell victim to black on white crime due to these politics.
No, the media is not over reporting disproportionally. If anything it's the other way around. One way you can know if a suspect is black is if the media avoids naming the perps race. This is even more pronounced in Europe.
There is a YouTube channel, AK Nation, a black man who covers all this, over and over. His entire channel is devoted to covering violent black crime in the news. He claims he only covers a fraction of what comes to his attention and this keeps him busy with daily content of the most bizarre cases. He wants a solution as much as any of us but finds himself at a loss to really find one. Even he speculates about the frontal cortex. One thing for sure, I see a tendency among blacks to take matters into there own hands, as if they had never heard of 911.
