Jesus dude, way to ign...,,There is no official definition as to what constitutes a mass shooting.
That article defines mass shooting as 5 dead excluding shooter, so they are playing politics with this one to get the desired outcome that THEY wanted.
Some people define mass shooting as more than 3 people getting shot with no requirements for fatalities.
Until we have a solid and agreed upon definition of what constitutes a mass shooting it is pointless to do studies as depending on the definition getting used for said study each study will come up with a different conclusion.
So yeah, that study is pointless and to further note you are more likely to die from medical malpractice than firearms, so i'd rather AMA and etc sort that issue out before getting on their high horse.
Ah fuck it, whatever.
