“The answer was Stellar Wind. The NSA would eavesdrop freely against Americans and aliens in the United States without probable cause or search warrants. It would mine and assay the electronic records of millions of telephone conversations—both callers and receivers—and the subject lines of e-mails, including names and Internet addresses. Then it would send the refined intelligence to the Bureau for action. Stellar Wind resurrected Cold War tactics with twenty-first-century technology. It let the FBI work with the NSA outside of the limits of the law. As Cheney knew from his days at the White House in the wake of Watergate, the NSA and the FBI had worked that way up until 1972, when the Supreme Court unanimously outlawed warrantless wiretaps. Stellar Wind blew past the Supreme Court on the authority of a dubious opinion sent to the White House the week that the Patriot Act became law. It came from John Yoo, a thirty-four-year-old lawyer in the Justice Department’s Office of Legal Counsel who had clerked for Justice Clarence Thomas. Yoo wrote that the Constitution’s protections against warrantless searches and seizures did not apply to military operations in the United States. The NSA was a military agency; Congress had authorized Bush to use military force; therefore he had the power to use the NSA against anyone anywhere in America. The president was “free from the constraints of the Fourth Amendment,” Yoo wrote. So the FBI would be free as well.”
