The facts of the case are pretty straightforward. Abdallah Higazy — an Egyptian — was staying in a hotel in New York City on September 11, 2001, which was evacuated when the planes hit the towers. Three months after the evacuation, Higzay returned to the hotel to claim his personal effects and was arrested by the FBI. A hotel security guard asserted that he had found a device that allows you to communicate with airline pilots in the closet of Higzay's room.
After initially denying any knowledge of the device, Higzay confessed to involvement in the 9/11 conspiracy. Luckily for him, an airline pilot returned to the hotel and asked for his radio back. The pilot had never heard of Higazy, had no contact with him. The radio had been a legitimate device owned by an airline pilot. As a consequence, Higazy is released and decides to sue the FBI for infringing his Fifth Amendment rights.
The Second Circuit renders a decision which permits the lawsuit, and explains what happened. Higazy was told that unless he confessed, his family in Egypt would be given to the Egyptian government for torture.
