re: Gun control in Europe is almost total. Hasn't stopped mass shooting attacks like Las Vegas

This is all stupid. We have this same tired debate everytime something like this happens. The difference is, gun control data in other countries has proved the American left dead wrong on gun control which is why the narrative has shifted to "mass shootings" and not gun crime. Internationally, there is poor correlation between gun ownership and gun homicides. The areas with the strictest control are often the most deadly.
