The attacks in Nice and Paris are the French equivalent of 9/11. They’re acts of war and are really outliers in statistics. You can’t really use these attacks as an argument against gun control. In day to day life there are 0.21 homicides by gunfire for 100k inhabitants per year in France and 3.6 in the US (source: wikipedia). I think the real argument is there... But then again, as a Frenchman most of American politics are more and more foreign and impossible to understand to me (gun law, healthcare...)
