Newt loves the Constitution except when someone thinks somebody is 'bringing a nuclear weapon into the U.S.' I guess that would be the Newtclear Option.
Ron Paul thinks the PATRIOT Act is unconstitutional, and thinks we got Timothy McVeigh without ever violating his Constitutional rights. He alluded to the Benjamin quote; you don't need to sacrifice liberty for security.
Newt says in counterpoint, McVeigh succeeded. Of course, he didn't use a nuclear weapon...
Paul points out that you might prevent crime by becoming a police state, but the real crime will be against the American people.
