Auditing Shooting Rampage Statistics - Daily Anarchist

Last week I posted a graphic on Facebook claiming the average number of people killed in mass shootings when stopped by police is 18.25, and the average number of people killed in a mass shooting when stopped by civilians is 2.2. I based it on 10 shootings I found listed on some timeline somewhere. I honestly don't even remember where. I presented the case studies in a blog post on the Silver Circle blog and I did the math myself.

The graphic was met with great enthusiasm and much skepticism. Leave it to Facebook users to demand an audit on a meme. So, I started over, only much more meticulous this time. I compiled and analyzed 93 shootings, noting my methodology, and I am now prepared to present my findings, complete with links to the data. But here's a spoiler… It's not that different.

The average number of people killed in mass shootings when stopped by police is 14.3

The average number of people killed in a mass shooting when stopped by a civilian is 2.3.
