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?
The majority of modern firearms are drop proof. I think a more realistic example would be a negligent discharge because the owner failed to empty the gun before cleaning it. (Both are negligence, you’re just not likely to have a dropped gun fire if it was made in the last 120 years or so)
