Please please PLEASE: this question is made from a place of pure curiosity, with no political biases intended. I’m asking because restrictions and prohibitions puts a pressure on the market since the demand never ceases, and someone interested in supply for that demand will do it for massive profits - no matter what. Wouldn’t it be the case for any product, be it drugs, alcohol or guns?
Eh, it would have little effect in the US, though only for a decade or three. Once a new generation came along that wouldn’t fetishize the pewpew too much, and give 'em enough time to sell/dispose of grandpa’s guns, I’m sure gun crimes would fall to levels similar to like, Australia.
