Second Amendment

The Second Amendment protects a right to keep and bear arms.

Definition

The Second Amendment states that a well-regulated militia is necessary to a free state and that the right of the people to keep and bear arms shall not be infringed.

Why It Matters

It is central to debates over individual gun rights, public safety, and permissible regulation.

How It Works

Courts evaluate firearms laws against constitutional text, history, and precedent.

History

Ratified in 1791, it reflected concerns about militias, standing armies, self-defense, and civic arms. Supreme Court decisions have recognized an individual right while allowing some regulation.

Example

A law prohibiting firearm possession by a broad class may face Second Amendment review.

Common Misconceptions

  • The amendment forbids every firearm regulation.
  • It applies only to organized military units.
  • Its legal meaning has never been disputed.
