Blacks in the United States have a murder rate that is nearly eight times the white murder rate.
Those who blame this on white racism cannot explain why the Civil Rights Act of 1964 and the War on Poverty declared the same year were followed by five years of black ghetto rioting, and more enduring increases in black crime.
Civilization selects genetically for obedience to the law, but the process is evolutionary and requires centuries. During most of history in civilized countries criminals were killed at the scene of the crime, they died in custody, or they were executed. The few children some of them had rarely lived to adulthood. Thus, crime genes were removed from the gene pools of civilized nations. The two civilized nations of whites and Orientals have practiced civilization the longest, so we have the lowest crime rates, even when we are poor.
I am defining a civilization as a city based society where the government has an effective monopoly on the legitimate use of violence. Tribes exist when the government is weak, ineffectual, or does not exist. In a tribal environment all men fight in the wars. The most effective warriors have more than one wife, and more sons who inherit their violent inclinations and aptitudes. In a tribal environment men are expected to avenge wrongs done to them, their friends, and their relatives. This also selects genetically for physical aggression. These genetic inclinations and aptitudes often lead to criminal behavior when a tribal people is introduced to civilization.
A criminal justice system that is effective for the two civilized races is insufficiently harsh for the other races. Before the civil rights movement this was understood in the United States, and especially in the South. This is why, when a white man and a black man committed the same crime, the black man was sentenced to more punishment.
The civil rights movement was well intended. I supported it as a child, a teenager, and a young adult. Unfortunately most Negroes have not lived up to the hopes white liberals felt for them at the beginning of the civil rights movement. To the contrary, they have verified arguments segregationists presented against the civil rights movement.
