Although the number of cops charged with murder or manslaughter sharply spiked last year, not a single officer was convicted for these unjustified deaths. With less cops killed in the line of duty in 2015, the number of people killed by police increased yet again.

The accumulated number of people killed by police in the U.S. last year remains between 986 and 1,200, with The Guardian currently totaling 1,138 victims. Although many disagree on the exact number of fatalities caused by cops, most concur that 2015 saw an escalation in both the total of people killed by police and the number of officers charged with murder or manslaughter.

Within the last decade, an average of five cops per year have been charged with murder or manslaughter in fatal on-duty shootings. Last year, that number more than tripled as 18 cops were arrested for unjustified shootings.
