It's also important to note that police shootings are just a subset of all police-involved deaths, which can include deaths by taser or vehicle, or the deaths of suspects in police custody.
A Guardian database of those deaths puts the total police-involved killing number at 464 for the year so far. If that rate holds, it would add up to over 1,100 police-involved killings for the calendar year. That's more than the number of people who die in the U.S. annually from spider bites, snake bites, lightning, dog bites, floods, storms, boating accidents and airplane accidents -- combined.
Correction: A previous version of this piece incorrectly stated that the Gun Violence Archive data includes deaths by suicide. Their data only counts suicides if they are part of a murder-suicide or a suicide at a police standoff.
