The President and the former Vice President could hardly disagree more on the right and wrong policies for keeping America safe. In dueling speeches today, they advanced their views and repudiated each other on issues including interrogations, Guantánamo Bay and the Constitution. Speaking at the National Archives, Obama said he'll protect the nation while preserving the rule of law. Cheney spoke at the American Enterprise Institute, where he said critics of tough anti-terrorist measures "distort the truth." We talk to reporters and others about today's quasi-debate. Will it change perceptions of the past? Will it help shape the future?
