We really have no way of knowing how prevalent mass attacks on the public have been throughout history. Since violent crime rates are historically low overall why be myopic about one form of it?
As for creative problem solving, there's nothing terribly creative about banning weapons and that's what we get from the left. What else has come from that side of the aisle with any vigor?
Infant mortality in the US is
6.5 per 1,000 live births.
Firearms homicide rate is 3.6 per 100,000 people. Dividing the first number by the second number respectively, we get percentages of .0065 for the births and .000036 for the gun murders. Let's say there's
4 million babies born each year. 4 million multiplied by our percentage is 26,000 dead infants. Using a population of 350 million and multiplying it by our percentage we get 12,600 gun murders. We know that
less than 1% of gun homicides are mass shootings. That gives us like 100 mass shooting deaths per year. Interesting how minuscule number is some huge epidemic and the far greater one is a problem that's been "conquered".
