Today marks the anniversary of the historic DC v. Heller Supreme Court case.
The Supreme Court's decision in Heller established the individual's right to keep and bear arms in federal enclaves like the District of Columbia, but it did not prevent states from continuing to put blanket restrictions on firearms. The right to keep and bear arms was not fully incorporated to the states until 2010, in McDonald v. Chicago.
