The right of ordinary citizens to possess weapons is the most extraordinary, most controversial, and least understood of those liberties secured by Englishmen and bequeathed to their American colonists. It lies at the very heart of the relationship between the individual and his fellows, and between the individual and his government.
It was during the eighteenth century - a period of boastful satisfaction with the nice balances within the English constitution - that Englishmen came to accept the Whig view of the utility of an armed citizenry. The armed citizen was not only affirmed to be protecting himself but, together with his fellows, provided the ultimate check on tyranny.
The argument that today's National Guardsmen, members of a select militia, would constitute the only persons entitled to keep and bear arms has no historical foundation.
