“There are no real consequences for committing property crimes anymore,” Los Angeles Police Lt. Armando Munoz told Downtown News earlier this month, “and the criminals know this.” The Milwaukee district attorney, John Chisholm, is diverting many property and drug criminals to rehabilitation programs to reduce the number of blacks in Wisconsin prisons; critics see the rise in Milwaukee crime as one result.

If these decriminalization and deincarceration policies backfire, the people most harmed will be their supposed beneficiaries: blacks, since they are disproportionately victimized by crime. The black death-by-homicide rate is six times higher than that of whites and Hispanics combined. The killers of those black homicide victims are overwhelmingly other black civilians, not the police. The police could end all use of lethal force tomorrow and it would have at most a negligible impact on the black death rate. In any case, the strongest predictor of whether a police officer uses force is whether a suspect resists arrest, not the suspect’s race.

Contrary to the claims of the “black lives matter” movement, no government policy in the past quarter century has done more for urban reclamation than proactive policing. Data-driven enforcement, in conjunction with stricter penalties for criminals and “broken windows” policing, has saved thousands of black lives, brought lawful commerce and jobs to once drug-infested neighborhoods and allowed millions to go about their daily lives without fear.

To be sure, police officers need to treat everyone they encounter with courtesy and respect. Any fatal police shooting of an innocent person is a horrifying tragedy that police training must work incessantly to prevent. But unless the demonization of law enforcement ends, the liberating gains in urban safety over the past 20 years will be lost.
