The FBI reports that 8.5 people are murdered with knives, blunt objects and bare hands for every one fatally shot with any type of rifle.
So to be safe we obviously need to require not the elimination of assault rifles (which are but one undefined and undefinable rifle category) but real disarmament -- amputations . . . not necessarily of all arms as called for by extremists but just the more moderate mandatory removal of all those lethal hands, at least to start with. We can always move higher up and lop off more of those dangerous limbs later if necessary.
