Yes, Mass Shootings Are Occurring More Often
New research from Harvard shows a chilling rise in public mass shootingsand debunks a popular claim that they haven't increased.
Though mass shootings make an outsize psychological impact, they are a tiny fraction of the nation's overall gun violence, which takes more than 30,000 lives annually. Rather than simply tallying the yearly number of mass shootings, Harvard researchers Amy Cohen, Deborah Azrael, and Matthew Miller determined that their frequency is best measured by tracking the time between each incident. This method, they explain, is most effective for detecting meaningful shifts in relatively small sets of data, such as the 69 mass shootings we documented. Their analysis of the data shows that from 1982 to 2011, mass shootings occurred every 200 days on average. Since late 2011, they found, mass shootings have occurred at triple that rateevery 64 days on average.
...
There has never been a clear, universally accepted definition of "mass shooting." The data we collected includes attacks in public places with four or more victims killed, a baseline established by the FBI a decade ago. We excluded mass murders in private homes related to domestic violence, as well as shootings tied to gang or other criminal activity. (Qualitative consistency is crucial, even though any definition can at times seem arbitrary. For example, by the four-fatalities threshold neither the attack at Ft. Hood in April nor the one in Santa Barbara in May qualifies as a "mass shooting," with three victims killed by gunshots in each incident.) A report from the FBI on gun rampages, issued in late September, includes attacks with fewer than four fatalities but otherwise uses very similar criteria.
James Alan Fox, a widely quoted researcher from Northeastern University, has argued that mass shootings are not on the rise, and that they are too rare to merit significant policy changes. As he put it recently in an interview with CNN's Jake Tapper: "We treasure our personal freedoms in America, and unfortunately, occasional mass shootings, as horrific as they are, is one of the prices that we pay for the freedoms that we enjoy."

(21,002 posts)1. There is a problem with those graphs...
as they claim the FBI baseline "The data we collected includes attacks in public places with four or more victims killed, a baseline established by the FBI a decade ago" which as they note would not include notable incidents "by the four-fatalities threshold neither the attack at Ft. Hood in April nor the one in Santa Barbara in May qualifies as a "mass shooting"", yet those incidents are on the graphs.
If the qualifying data is inconsistent with the standard claimed, then the resulting conclusion is meaningless.

With stats like these it's hard to understand why banners want to take our rights away.
