In responding to a question about the vulnerabilities of the United States when it comes to terrorist attacks, Biden said that the radical, lone wolves have been the most difficult to catch. But he said America shouldn't change its values, how it treats people abroad or people coming into the United States. Nor should America adopt policies that keep people from freely walking down the street without being frisked by police or carrying identification cards, he said.
"The moment we change any of those things, that's when they win," Biden said. "Because they don't see how you can have a society that is not ordered and regimented and wedded to an orthodoxy that is theirs. That's the point that bothers them most about us."
McCain followed up by saying that those who tortured U.S. prisoners, in violation of the Geneva convention, should be exposed and be held responsible to prevent repeated abuses.
Biden agreed with the man once held as a prisoner of war during the Vietnam War. He said the internal debate in Congress and at the White House is how things got to that point, but it's not yet resolved.
"I think the only way you excise the demons is you acknowledge what happened, straightforward," Biden said.
