D.C. v. Heller

Explanation:

The Second Amendment consists of two parts: the prefatory clause that states “A well regulated Militia, being necessary to the security of a free State”, and the operative clause that says “the right of the people to keep and bear Arms shall not be infringed”. Through the years, the second clause has been the most controversial and debated in the Court.

However, In the District of Columbia v. Heller case (2008), the Supreme Court ruled that responsible citizens (thus, felons and the mentally ill excluded) could keep and bear arms for self-defense only and it should be kept in the home, but they could not carry dangerous and unusual weapons. The quote provided, then, is from and reflects the main idea of this cases.
