Certainly one of the chief guarantees of freedom under any government, no matter how popular and respected, is the right of the citizen to keep and bear arms. This is not to say that firearms should not be very carefully used and that definite rules of precaution should not be taught and enforced. But the right of the citizen to bear arms is just one more safeguard against a tyranny which now appears remote in America, but which historically has proved to be always possible.
—Hubert Humphrey, 1960
"For the nation’s elites, the Second Amendment has become the Rodney Dangerfield of the Bill of Rights, constantly attacked by editorial writers, police chiefs seeking scapegoats, demagoging politicians, and most recently even by Rosie O’Donnell, no less. It is threatened by opportunistic legislative efforts, even when sponsors acknowledge their proposed legislation would have little impact on crime and violence.
Professional champions of civil rights and civil liberties have been unwilling to defend the underlying principle of the right to arms. Even the conservative defense has been timid and often inept, tied less, one suspects, to abiding principle and more to the dynamics of contemporary Republican politics. Thus a right older than the Republic, one that the drafters of two constitutional amendments - the Second and the Fourteenth - intended to protect, and a right whose critical importance has been painfully revealed by twentieth-century history, is left undefended by the lawyers, writers, and scholars we routinely expect to defend other constitutional rights."
Robert J. Cottrol's essay on the right to keep and bear arms is the single finest work of its kind I have ever read: A Liberal Democrat's Lament.
