The Constitution is plain.
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 two parts
1. Militia Clause (prefatory clause)
“A well regulated Militia, being necessary to the security of a free State…”
This explains a purpose or rationale:
In the late 1700s, “militia” generally meant citizen-soldiers
“Well regulated” meant properly functioning / trained, not heavily restricted in the modern sense
2. Operative Clause
“…the right of the people to keep and bear Arms, shall not be infringed.”
This is the actual legal protection:
Refers to “the people” (same phrase used in the 1st and 4th Amendments)
Protects an existing right to possess and carry arms.
How courts interpret it
The key modern interpretation comes from:
District of Columbia v. Heller
McDonald v. City of Chicago
What those decisions say:
The Militia Clause does not limit the right only to militia service
The right is individual, not just collective
However, the right is not unlimited (certain permitting regulations are allowed).
Disagreement usually centers on:
Whether the Militia Clause limits the right or simply explains one reason for it. Modern Supreme Court doctrine treats it as explanatory, not restrictive
