As usual, another good op-ed by Glenn Greenwald in The Guardian. Greenwald argues against a Krauthammer piece in The Post where Krauthammer argues that the American Constitution does not apply to American citizens when they leave the country. But Greenwald cites a 1957 Supreme Court ruling that says that this is not true. He further states that Krauthammer and his neo-con cohorts are just trying to rebuke the points made by Sen. Rand Paul during his one-man filibuster a few days ago.
