concerning frequently cited United States v. Sinclair, commonly referred to as the Keith Decision, in 1972.

Judge Keith found that then-President Richard Nixon and then Attorney General John Mitchell could not engage in warrantless wiretap surveillance of three individuals suspected of conspiring to destroy government property because the surveillance was in violation of the Fourth Amendment. The decision was affirmed by the Sixth Circuit and unanimously upheld by the U.S. Supreme Court.

When are you going to show me how it is legal for a president to SPY on US CITIZENS without a WARRANT?? without giving me a biased opinion editorial piece that is suggesting W should be let off the hook.
