Eric Garner, Michael Brown, Akai Gurley, Walter Scott, Samuel DuBose—the list of high-profile killings by police in the U.S. continues to grow.* When this story went to press in September, officers had already shot and killed 680 people in 2015, according to a database maintained by the Washington Post. By its count, only 6 percent of the white suspects were unarmed, compared with 14 percent of the black victims. If the numbers reflected U.S. demographics, unarmed white deaths should be twice as high—and unarmed black deaths should be three times lower.
