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.
A lot of people are getting confused by the words in here, so I'll break it down for people to better understand the whole meaning of it.
"A well regulated Militia, being necessary to the security of a free State" This is the big one a lot of people are getting confused on. Some think that the term Militia, means, should mean, or is superseded by the National Guard. It does not. The term militia was commonly used then to refer to a military force composed of ordinary citizens to provide defense, emergency law enforcement, or paramilitary service, in times of emergency without being paid a regular salary or committed to a fixed term of service. The National Guard, is more an adjunct to the regular Army. Yes, it is composed of ordinary citizens, and called upon in times of emergency, to provide defense, emergency law enforcement, or military service, in times of emergency, but they are also committed to a term of service.
Let's look at the last part,
"the right of the people to keep and bear Arms, shall not be infringed."
Seems pretty clear there, no unambiguous language at all.
So lets put it all together.
"A well regulated Militia, (ordinary citizens to provide defense, emergency law enforcement, or paramilitary service, in times of emergency without being paid a regular salary or committed to a fixed term of service,) being necessary to the security of a free State, (everyone should help defend against foreign invaders, and domestic, tyrants, to keep everyone's rights) the right of the people to keep and bear Arms, shall not be infringed."
What are people not getting here?
