Here is the language of the Second Amdendment to the U.S. Constitution:

"Amendment II

A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed."



Note the language that this militia is "necessary to the security of a free state". This means that this militia is ABLE TO DEFEND AGAINST FOREIGN AND DOMESTIC ENEMIES IN WARFARE...ie, be able to defend against a modern army of the day.

The original meaning of the language "well regulated" here basically means "properly trained and equipped." Also, the original meaning of the term "militia" is basically "every able bodied male who could serve in the army."

Thus, putting this Amendment into "modern" language, it is saying:

"A properly equipped and trained population of able-bodied men, being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed."
