In the last 5 years, police officers have killed 3,400 citizens who were not fleeing from them.
The Washington Post has been compiling a database of every fatal shooting in the United States by a police officer in the line of duty since January 1, 2015. The open-source database on Github tracks the following data: race of the deceased, the circumstances of the shooting, whether the person was armed and whether the victim was experiencing a mental-health crisis, and more than a dozen additional details. One metric is whether the person killed was fleeing from police officers. In 3,400 out of 5,400 instances (63%), the person killed was not fleeing.
