The right to keep and bear arms is a lot like the right to freedom of speech. In each case, the Constitution expressly protects a liberty that needs to be insulated from the ordinary political process. Neither right, however, is absolute. The First Amendment, for example, has never protected perjury, fraud, or countless other crimes that are committed through the use of speech. Similarly, no reasonable person could believe that violent criminals should have unrestricted access to guns, or that any individual should possess a nuclear weapon.
