A new study confirms that black men and women are treated differently in the hands of law enforcement. They are more likely to be touched, handcuffed, pushed to the ground or pepper-sprayed by a police officer, even after accounting for how, where and when they encounter the police.
But when it comes to the most lethal form of force — police shootings — the study finds no racial bias.
“It is the most surprising result of my career,” said Roland G. Fryer Jr., the author of the study and a professor of economics at Harvard. The study examined more than a thousand shootings in 10 major police departments, in Texas, Florida and California.
He and a group of student researchers spent about 3,000 hours assembling detailed data from police reports in Houston; Austin, Tex.; Dallas; Los Angeles; Orlando, Fla.; Jacksonville, Fla.; and four other counties in Florida.
They examined 1,332 shootings between 2000 and 2015, systematically coding police narratives to answer questions such as: How old was the suspect? How many police officers were at the scene? Were they mostly white? Was the officer at the scene for a robbery, violent activity, a traffic stop or something else? Was it nighttime? Did the officer shoot after being attacked or before a possible attack? One goal was to figure out whether police officers were quicker to fire at black suspects.
In officer-involved shootings in these cities, officers were more likely to fire their weapons without having first been attacked when the suspects were white. Black and white civilians involved in police shootings were equally likely to have been carrying a weapon. Both of these results undercut the idea that the police wield lethal force with racial bias.
And in the arena of “shoot” or “don’t shoot,” Mr. Fryer found that, in tense situations, officers in Houston were about 20 percent less likely to shoot a suspect if the suspect was black. This estimate was not very precise, and firmer conclusions would require more data. But, in a variety of models that controlled for different factors and used different definitions of tense situations, Mr. Fryer found that blacks were either less likely to be shot or there was no difference between blacks and whites.
