The senator talks about the Second Amendment and D.C. v. Heller. "Gun ownership is among those liberties that deserves a passionate defense," says Arizona Senator John McCain, noting that for reasons that seem "more political than constitutional," anti-gunners throughout history have tried to separate it from the Bill of Rights as "archaic" and "unnecessary." Rather than try to attack the hallowed Constitution, those lobbyists instead tried to separate the Second Amendment from the rest of the first ten amendments as the only one referring to a "collective" freedom. But since the Heller decision, "the Second Amendment is now, as one observer put it, a normal part of the Bill of Rights," says McCain. However, the senator warns that those who believe in the right to keep and bear arms must remain vigilant.
