"From 1980 to 2013, there were 2,269 officers killed in felonious incidents, and 2,896 offenders. The racial breakdown of offenders over the 33-year period was on par with the 10-year period: 52 percent were white, and 41 percent were black."
Also from the article: "The black population in America ranged from 11.6 percent to 13 percent between 1980 to 2013. Compared to that percentage in the population, the percentage of black offenders who killed police officers appears to be disproportionately high. But blacks tend to be concentrated in the South and in cities; some large urban areas, such as Detroit, have majority African American populations. About 51 percent of police killings were in cities and counties with a population of less than 250,000."
