The Washington Post has won the Pulitzer Prize for national reporting. The Post’s staff was honored Monday for creating and using a national database to illustrate how often and why police shoot to kill. The Post found that in 2015, on-duty police officers shot and killed 990 people nationwide. It reported that unarmed black men were seven times more likely to die at the hands of police officers than unarmed whites were. More than 50 of the officers had killed someone before/Associated Press. See who else won Pulitzer Prizes here.
