Between 1976 and 2005 blacks com­mitted more than half of all murders in the United States

The black arrest rate for most offenses — including robbery, aggravated assault and property crimes — is still typically two to three times their representation in the population. Blacks as a group are also overrepresented among persons arrested for so-called white-collar crimes such as counterfeiting, fraud and embezzlement. “Even allowing for the existence of discrimination in the criminal justice system, the higher rates of crime among black Americans cannot be denied,” wrote James Q. Wilson and Richard Herrnstein in their classic 1985 study, Crime and Human Nature. “Every study of crime using official data shows blacks to be overrepresented among persons arrested, convicted, and imprisoned for street crimes. The overrepresentation of blacks among arrested persons persists throughout the criminal justice system,” wrote Wilson and Herrnstein. “Though prosecutors and judges may well make discriminatory judgments, such decisions do not account for more than a small fraction of the overrepresentation of blacks in prison.” Others have also noticed the the excessive amount of black criminality. “High rates of black violence in the late twentieth century are a matter of historical fact, not bigoted imagination,” wrote William Stuntz, a Harvard law professor, in his 2011 book, The Collapse of American Criminal Justice. "The trends reached their peak not in the land of Jim Crow but in the more civilized North, and not in the age of segrega­tion but in the decades that saw the rise of civil rights for African Americans — and of African American control of city governments.” Black crime and incarceration rates spiked in the 1970s and ’80s in cities such as Baltimore, Cleveland, Detroit, Chicago, Philadelphia, Los Angeles and Washington under black mayors and black police chiefs. Some of the most violent cities in the United States today are run by blacks.
