BAGHDAD—The U.S. was forced to free accused war criminal Saddam Hussein Monday following the revelation that the former Iraqi dictator had been arrested in an illegal search. "American special forces neglected to obtain proper warrants before dragging Mr. Hussein from his hiding place outside of Adwar," Iraqi prime minister Iyad Allawi said in a morning press conference. "In accordance with international law, the Americans had no choice but to free him." Hussein, who is still named as the defendant in hundreds of outstanding civil cases, said his release was proof that the system works.
