Wiretapping's true danger

In 1945, Harry Truman had the FBI wiretap Thomas Corcoran, a member of Franklin D. Roosevelt's "brain trust" whom Truman despised and whose influence he resented. Following the death of Chief Justice Harlan Stone the next year, the taps picked up Corcoran's conversations about succession with Justice William O. Douglas. Six weeks later, having reviewed the FBI's transcripts, Truman passed over Douglas and the other sitting justices to select Secretary of the Treasury (and poker buddy) Fred Vinson for the court's top spot.

"Foreign intelligence" was often used as a pretext for gathering political intelligence. John F. Kennedy's attorney general, brother Bobby, authorized wiretaps on lobbyists, Agriculture Department officials and even a congressman's secretary in hopes of discovering whether the Dominican Republic was paying bribes to influence U.S. sugar policy. The nine-week investigation didn't turn up evidence of money changing hands, but it did turn up plenty of useful information about the wrangling over the sugar quota in Congress -- information that an FBI memo concluded "contributed heavily to the administration's success" in passing its own preferred legislation.

In the FISA debate, Bush administration officials oppose any explicit rules against "reverse targeting" Americans in conversations with noncitizens, though they say they'd never do it.

But Lyndon Johnson found the tactic useful when he wanted to know what promises then-candidate Richard Nixon might be making to our allies in South Vietnam through confidant Anna Chenault. FBI officials worried that directly tapping Chenault would put the bureau "in a most untenable and embarrassing position," so they recorded her conversations with her Vietnamese contacts.

Johnson famously heard recordings of King's conversations and personal liaisons with various women. Less well known is that he received wiretap reports on King's strategy conferences with other civil rights leaders, hoping to use the information to block their efforts to seat several Mississippi delegates at the 1964 Democratic National Convention. Johnson even complained that it was taking him "hours each night" to read the reports.

Few presidents were quite as brazen as Nixon, whom the Church Committee found had "authorized a program of wiretaps which produced for the White House purely political or personal information unrelated to national security." They didn't need to be, perhaps. Through programs such as the National Security Agency's Operation Shamrock (1947 to 1975), which swept up international telegrams en masse, the government already had a vast store of data, and presidents could easily run "name checks" on opponents using these existing databases.
