Your argumentdoesn't hold water.
To say that the 2nd Amendment doesn't allow for the private ownership of firearms is a blatant lie. Every one of the Founding Fathers owned firearms, as did most people living in the newly formed country. Not once did they try to outlaw the sale, possession or ownership of firearms. No serious attempts at registration or regulation of firearms occurred until the 1930s, nearly 150 years after the Constitution was enacted. The actions (or lack thereof) of the Founders concerning firearms, speak to their intentions.
