Wiretapping and FISA, Explained

Why did the President authorize the NSA to conduct surveillance on U.S.-based communications?

People familiar with the process say the problem is not so much with the court itself as with the process required to bring a case before the court. "It takes days, sometimes weeks, to get the application for FISA together," says one source. "It's not so much that the court doesn't grant them quickly, it's that it takes a long time to get to the court. Even after the Patriot Act, it's still a very cumbersome process. It is not built for speed, it is not built to be efficient. It is built with an eye to keeping [investigators] in check." And even though the attorney general has the authority in some cases to undertake surveillance immediately, and then seek an emergency warrant, that process is just as cumbersome as the normal way of doing things.

Lawmakers of both parties recognized the problem in the months after the September 11 terrorist attacks. They pointed to the case of Coleen Rowley, the FBI agent who ran up against a number roadblocks in her effort to secure a FISA warrant in the case of Zacarias Moussaoui, the al Qaeda operative who had taken flight training in preparation for the hijackings. Investigators wanted to study the contents of Moussaoui's laptop computer, but the FBI bureaucracy involved in applying for a FISA warrant was stifling, and there were real questions about whether investigators could meet the FISA court's probable-cause standard for granting a warrant. FBI agents became so frustrated that they considered flying Moussaoui to France, where his computer could be examined. But then the attacks came, and it was too late.

It's all about speed.
