Understanding the Second Amendment:
“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.”
The term “well-regulated” was commonly used before 1789 and continued to be for a century after. It described something being in proper working order, calibrated correctly, and functioning as expected.
The term “militia” refers to all citizens capable of military service. The National Guard did not replace the militia, as clarified by the Militia Act of 1903. The National Guard is the organized militia, while able-bodied men between 17 and 45 are part of the reserve militia. The Militia Act of 1903 repealed the requirement for men to provide their own firearm under the Militia Act of 1792.
The term “to keep and bear” is very easy to understand. “To keep” means to have or possess. “To bear” in this context means to carry and to hold. The phrase very simply means that you can have the item in your possession.
The term “shall not be infringed” means to wrongly limit or restrict. This acts on the previous phrase, “to keep and bear”. The language is clear and concise.
The Second Amendment, in more modern terms, would read like this: “A properly armed people are necessary for a state to be free and safe. American Citizens can have weapons in their possession, and you can't do anything about it.”
Understand this; The US Constitution is a limit on government, not citizens, and our rights don't end where your feelings begin. You have no right to infringe on our inalienable rights.
