Also, if you're ever interested in reading a good report that demonstrates that the US does NOT have the highest rate of mass shootings, etc., this is a good place to start:

The research paper is titled "Comparing the Global Rate of Mass Public Shootings to the U.S.’s Rate and Comparing Their Changes Over Time" and it's a good one to reference when discussing "mass shootings" to dispel myths about the US experience.
Yeah that's really good data. I've seen that in this article before which is one I like to send to people who believe that nonsense about mass shootings being a uniquely American problem.
