CNN reports that phone conversations between Alaska Republican Senator Ted Stevens and an oil executive guilty of bribery were taped by the FBI. Was this surveillance under a court-approved warrant? If so, it indicates some probable cause for suspicion of Senator Stevens, one of the least progressive members of the U.S. Senate. If this surveillance occurred without a warrant, on the other hand, it indicates that regular citizens like you and I are more vulnerable to government surveillance than we might like to think. Keep your eye looking through that knothole as this mystery continues to play itself out.
