In a collaboration between The Marshall Project and The Upshot, Daniel Lathrop and Anna Flagg analyzed data for 400,000 homicides between 1980 and 2014.
In almost 17 percent of cases when a black man was killed by a non-Hispanic white civilian over the last three decades, the killing was categorized as justifiable, which is the term used when a police officer or a civilian kills someone committing a crime or in self-defense. Overall, the police classify fewer than 2 percent of homicides committed by civilians as justifiable. The disparity persists across different cities, different ages, different weapons and different relationships between killer and victim.
