Why are prison populations dramatically inverse in proportion to the racial demographics of the U.S.?

This were the major findings about this question:

• There are dramatic race differences in crime rates. Asians have the lowest rates, followed by whites, and then Hispanics. Blacks have notably high crime rates. This pattern holds true for virtually all crime categories and for virtually all age groups.
• In 2013, a black was six times more likely than a non-black to commit murder, and 12 times more likely to murder someone of another race than to be murdered by someone of another race.
• In 2013, of the approximately 660,000 crimes of interracial violence that involved blacks and whites, blacks were the perpetrators 85 percent of the time. This meant a black person was 27 times more likely to attack a white person than vice versa. A Hispanic was eight times more likely to attack a white person than vice versa.
• In 2014 in New York City, a black was 31 times more likely than a white to be arrested for murder, and a Hispanic was 12.4 times more likely. For the crime of “shooting” — defined as firing a bullet that hits someone — a black was 98.4 times more likely than a white to be arrested, and a Hispanic was 23.6 times more likely.
• In 2015, a black person was 2.45 times more likely than a white person to be shot and killed by the police. A Hispanic person was 1.21 times more likely. These figures are well within what would be expected given race differences in crime rates and likelihood to resist arrest.
• Blacks were the only group to see a reduction in incarceration rates, but the reduction was small, and blacks remained far more likely to be incarcerated for violent crimes than any other group. The black violent-crime incarceration rate in 2013 was 6.3 times that of the white rate. This does not necessarily mean that blacks are 6.3 times more likely to commit violent crimes, because prison time depends on the severity of the crime as well as prior record.

The past two years have seen unprecedented concern about racial bias in law enforcement. Deaths of young black men at the hands of the police led to serious rioting in Ferguson, Missouri, and in Baltimore. These and other deaths gave rise to the Black Lives Matter movement, which has carried out hundreds of demonstrations across the country and even in Canada. It is widely assumed that the police and the courts are strongly biased — certainly against blacks, and probably against Hispanics.

This problem cannot be fully understood by concentrating on a few cases, no matter how disturbing they may first appear. There were an estimated 11,300,000 arrests in the United States in 2013, the overwhelming majority of which were carried out properly. It is only in a larger context that we can draw conclusions about systemic police bias or misbehavior. This larger context is characterized by two fundamental factors. The first is that different racial groups commit crime at strikingly different rates, and have done so for many years. The second is that crime, overall, has declined dramatically over the last 20 years. Only after considering these points is it possible to draw well-founded conclusions about police bias.

One of the reasons that I believe non-whites are incarcerated more is that we have a stereotypes. If you don't know what I mean by that, check out this video and see the reality: 

See? Now we wonder if there'd be more whites incarcerated if stereotypes didn't exist.
