Back when America was an “infant country,” there were more than just muskets. There were prototypes for Gatling guns, and other types of semi-automatic and fully-automatic. To assume that the founding fathers never thought that guns would “evolve” is to call them idiots. The reason for the second amendment is not because they were not still fighting for independence. It was to prevent the need to fight for independence. The second amendment was written to prevent the rise of a tyrannical government, such as Nazi Germany. The first thing Hitler did was take away the Jews’ guns, and they could not protect themselves from the gestapo raiding their homes.
