Police have killed more Americans on U.S. soil since the year 2000 than the Islamist terrorists.
At Vox, Anand Katakam created an interactive map with data from Fatal Encounters, a nonprofit working to build a national database of police killings. This database, and the map Vox created, shows that US police have killed at least 5,600 people since the year 2000. That's many more than have died in terrorist attacks on American soil.
A huge majority of the more than 5,600 deaths on the map are from gunshots, which is hardly surprising given that guns are so deadly compared to other tools used by police. There are also a lot of noticeable fatalities from vehicle crashes, stun guns, and asphyxiations. In some cases, people died from stab wounds, medical emergencies, and what's called "suicide by cop," when someone commits suicide by baiting a police officer into using deadly force.
Here's a full-page view of the interactive map.
