AT exactly 5 p.m. on March 13, 2007, just as I was preparing to leave my cubicle in Washington for the day, I got a phone call from the journalist Jonathan Landay of McClatchy Newspapers. To this day, I remember his exact words.

“One of your congressman’s constituents is being held in an Ethiopian intelligence service prison, and I think your former employer is neck-deep in this.”

The congressman was Rush Holt, then a Democratic representative from New Jersey, for whom I worked for 10 years starting in 2004. The constituent was Amir Mohamed Meshal of Tinton Falls, N.J., who alleges that he was illegally taken to Ethiopia, where he was threatened with torture by American officials. My “former employer” was the Central Intelligence Agency, but it soon became apparent that the agency “neck-deep in this” was the Federal Bureau of Investigation.

Eight years after Mr. Meshal’s rendition, his case ended up before a three-judge panel of the United States Court of Appeals for the District of Columbia. The questions hanging over the proceeding were: can the United States government allow, or even facilitate, the rendition of an American citizen to another country for interrogation? And can United States officials themselves conduct rendition and interrogations of American citizens, including threats of torture, on foreign soil?
