It's the stench of Bill O'Reilly's hard-core fascism. Bob Barr plays the sane one.
As Paul Craig Roberts put it:
Republicans and American conservatives regard civil liberties as coddling devices for criminals and terrorists. They assume that police and prosecutors are morally pure and, in addition, never make mistakes. An accused person is guilty, or government wouldn't have accused him. All of my life, I have heard self-described conservatives disparage lawyers who defend criminals. Such "conservatives" live in an ideal, not real, world.
