African Americans represent about 14% of the U.S. population, 54% of murder offenders, and 33% of the people killed by police. A 1985 Supreme Court ruling prohibits police from using deadly force unless "the officer has probable cause to believe that the suspect poses a significant threat of death or serious physical injury to the officer or others." From 2006 to 2015, 65 officers were charged in fatal shootings, and 11 were convicted. The U.S. is third-most populous nation in the world, with more than 320 million people, 900,000 law enforcement officers, and 14,000 murders per year. Hence, by focusing on selected events, the media can paint virtually any picture of violence in the United States.
