Ok, so let's say you ban Assault Rifles completely and they don't exist in civilians hands. Then another one of these tragedies happens using an Assault Rifle obtained illegally and then what do you do? Not only have you removed 2nd Amendment rights from law abiding citizens, these mass shootings still go on legal or not. It doesn't take an AR style platform to cause a mass shooting. Take Columbine for example, it occurred in April of 1999 during the Assault Weapons ban of 1994-2004. Note all the weapons used in Columbine were sawed off shotguns, 9mm semi auto rifle in a 10 Round magazine, and a 9mm handgun (No Assault Weapons were used). I am not being close minded whatsoever, but the argument that banning these weapons will stop all mass shootings is a false statement, there is no way to predict when these type of events will occur. You ignore all violent crime statistics, but pick out only cases where Assault Weapons are used. Assault weapons are used in such a small number of violent crimes that legally banning them will result in no added protection. I would like to see how you think this will make us any safer besides the statement that you can reload slower with other guns compared to the AR rifle, or "it holds more ammo in a magazine". Any average American can reload a semi auto pistol in 1-2 seconds, and they can be purchased with extended magazines.
