So far this year, 509 people have been shot and killed by police in the United States, according to The Washington Post’s Fatal Force database. Most had guns, and most were white, but a quarter were black — a disproportionate number, given the country’s African American population.

Yet police officers frequently arrest suspects armed with guns who have shot and killed one or more people, who have shot at or killed cops, who have threatened men, women and children. And they arrest them without incident or loss of more life, according to the letter of the law. I did a bit of research and found plenty of examples. And, not surprisingly, lots of those gunmen were white.
