"More gun crime PER PERSON" The gun crime in America is mainly do to the gun culture in the US, so it's not fair to compare to a nation without one. "And we wouldnt need Good Samaritans would guns if criminals had knifes. RN, criminals and Good Samaritans have guns. If they BOTH had knifes, it would be safer" If only people had knifes the most dangerous things by the standards of defense would be a knife, so at that point you would just have mass knife crime. You could also by a sword and be more dangerous than a guy with a knife.
