How Many Mass Shootings Are There, Really?

How Many Mass Shootings Are There, Really?
There is a big difference between 355 and 4. "On Wednesday, a Washington Post article announced that “The San Bernardino shooting is the second mass shooting today and the 355th this year.” Vox, MSNBC’s Rachel Maddow, this newspaper and others reported similar statistics. Grim details from the church in Charleston, a college classroom in Oregon and a Planned Parenthood clinic in Colorado are still fresh, but you could be forgiven for wondering how you missed more than 300 other such attacks in 2015. At Mother Jones, where I work as an editor, we have compiled an in-depth, open-source database covering more than three decades of public mass shootings. By our measure, there have been four “mass shootings” this year, including the one in San Bernardino, and at least 73 such attacks since 1982."
