The shooting death of a young black man by a white police officer in Ferguson, Missouri, last year touched off a national discussion about everything except the aberrant behavior of so many young black men that results in such frequent encounters with police....

Homicide is the leading cause of death for young black men in the U.S., and around 90 percent of the perpetrators are also black. Yet for months we've had protesters nationwide pretending that our morgues are full of young black men because cops are shooting them. Around 98 percent of black shooting deaths do not involve police. In fact, a cop is six times more likely to be shot by someone black than the opposite. The protestors are pushing a false anti-cop narrative, and everyone from the president on down has played along.

Any candid debate on race and criminal justice in this country would have to start with the fact that blacks commit an astoundingly disproportionate number of crimes. Blacks constitute about 13 percent of the population, yet between 1976 and 2005 they committed more than half of all murders in the U.S. The black arrest rate for most offenses--including robbery, aggravated assault, and property crimes--is typically two to three times their representation in the population. So long as blacks are committing such an outsized amount of crime, young black men will be viewed suspiciously and tensions between police and crime-ridden communities will persist. The U.S. criminal justice system, currently headed by a black attorney general who reports to a black president, is a reflection of this reality, not its cause. If we want to change negative perceptions of young black men, we must change the behavior that is driving those perceptions. But pointing this out has become almost taboo.
