A look at US police encounters resulting in black deaths

The police slayings of two black men after traffic stops are the focus of murder trials unfolding in two cities. They also are among a series of cases across the country that have raised a national debate over race and policing.

Former University of Cincinnati officer Ray Tensing is on trial in the 2015 fatal shooting of 43-year-old Sam DuBose. Former North Charleston, South Carolina, officer Michael Slager is on trial in the April 2015 shooting of 50-year-old Walter Scott. Both former officers are white.

Other cases of the deaths of blacks after police encounters range from the fatal shooting of a 12-year-old boy in a Cleveland recreation area in November 2014 to that of a 66-year-old woman in her Bronx, New York, apartment last month.
