I tend to get upset when the media uses the term "Assault Rifle" whenever a semi-automatic AR15 or an AK47 was used in a shooting. Mostly because the term is inaccurate. We all know civilian versions of these rifles do not have select fire capabilities. One question is whether full-auto and 3-shot-burst modes make these rifles a whole lot more powerful/deadly? In the context of mass-shootings probably not that much as the shooters don't encounter much resistance and full auto seems more a waste of ammo. Handguns are still at 75% of all mass shootings, and then we have 10% shot guns, 10% bolt action rifles, and only the remainder is semi-automatic rifles of any type.
