I think this is the best article I have seen on this topic: https://www.scientificamerican.com/article/6-things-to-know-about-mass-shootings-in-america/ https://www.scientificamerican.com/article/6-things-to-know-... Specifically the graph about halfway through the article that show the relationship between the number of guns and frequency of mass shootings, clearly the USA is a significant outlier. It's pretty compelling IMHO.
