Statistics are irrelevant. America is a violet country with lots of guns. The only solution is for every responsible adult to carry a sidearm at all times. Look at last shooting in TN. The gunman was not well-trained even if he had the element of surprise if the victims were armed he could kill one maybe two but not five. Regardless of how many fell the rest of poor Americans could take small measure of comfort in that they did not die defenseless.
