The recent police killings of Black civilians such as Breonna Taylor and George Floyd—and the mass protests in response—have refocused national attention on violence and racism in law enforcement. But to understand the problems you need to know the basics.

The United States is home to some 18,000 law enforcement agencies employing more than 900,000 sworn officers.
