From the U.S. Bureau of Justice, “Arrest related deaths.” 42% of persons who died during an arrest were white, 32% were black, and 20% were Hispanic. ( 2003-2009). Of the 98 million arrests, 4,813 resulted in deaths, 40% of which were homicide. 75% of those who died were involved in a violent crime.
So why is homicide for blacks at arrest out of proportion to their population? The offending rate for blacks is 34.4 per 100,000 compared to 4.5 per 100,000 for whites. Based on that figure, it looks like whites are more likely to be killed by police while committing a crime than blacks.
