You hardly need a calculator to figure out that 371/475 is less than 1.5 (!) people killed on average per mass shooting (along with four wounded or more). In other words, the average number of dead bodies per "mass" shooting — as redefined downwards — turns out to be between… one and two! And closer to one, at that! (And with the assailant being included nowadays, wouldn't that mean that a "mass" shooting might include one in which the only dead person turns out to be the criminal himself?!)
It takes an Erick Erickson to take an even deeper perspective on these "factual" statistics.
There are more than 300 million guns in private hands in the United States and more than 2 trillion rounds of ammunition in private hands. What we are seeing is not an out of control gun problem. In fact, mass shootings in the United States have fallen so much in the past century that the political left has insisted we redefine what a mass shooting is. It is all in the name of gun control.
The left will not talk about mental illness. The left will not talk about radical jihadism. The left only wants to talk about gun control. There is a very easy to understand explanation for this phenomenon
