CNN reports that Nicholas George was detained at Philly airport for five hours last summer because he had Arabic-language flashcards in his luggage. "George, 22, a senior at Pomona College in California, filed suit in federal court Wednesday against the Transportation Security Administration, the Philadelphia Police Department and the FBI. He says he was handcuffed and "abusively interrogated" by authorities at Philadelphia International Airport. The lawsuit, filed by the American Civil Liberties Union, alleges officials violated George's Fourth Amendment protections against unreasonable seizure and First Amendment rights to free speech. "Nick doesn't object and we don't object to the fact that he was searched closely, that his belongings were scrutinized," ACLU attorney Ben Wizner told CNN. "But once that's done, there's absolutely no justification for handcuffing him and locking him in a cell for several hours.""
