An anonymous reader writes: After a seven-year lawsuit costing nearly $4 million, a judge has concluded that Rahinah Ibrahim's student visa was revoked because an FBI agent checked the wrong box on a form. That simple human error resulted in the detention of a Rahinah Ibrahim, the revocation of her student visa years later and interruption of her PhD studies. The Bush and later Obama administrations obstructed the lawsuit repeatedly, invoking classified evidence, sensitive national security information and the state secrets privilege to prevent disclosure of how suspects are placed on the 'no-fly' list. The dispute eventually involved statements of support from James Clapper, Eric Holder and several other DOJ and TSA officials in favor of the government's case. The defendant was not allowed to enter the United States even to attend her own lawsuit trial and in a separate incident, her daughter, a US citizen, was denied entry to witness the trial as well. The case exemplifies how government secrecy can unintentionally transform otherwise easily corrected errors into a multi-year legal and bureaucratic nightmare and waste millions of taxpayer dollars in doing so.
