Philip Bump uses data from ShootingTracker.com, to show that “mass shootings — defined as incidents in which four or more people are shot — have happened hundreds of times over the last several years … Only once have seven days passed without a mass shooting and only once have eight days passed. Those are the longest spans — the latter happening in April of this year. Several times, six days have passed.”
Bump includes an update to his map showing the locations of the year’s mass shootings. Below: All of the shootings through Dec. 2 (as of 1 p.m. Pacific/4 p.m. Eastern).
“There have been incidents that meet the ShootingTracker standard in 46 states and in D.C. Florida, Illinois and California have had the most incidents. In each state, there have been at least 22 shooting incidents in which four or more people were shot.”
