Abdullah al-Kidd is a Kansas-born American citizen, a father, and a graduate of the University of Idaho where he was a star football player. And in 2003, he became the victim of the FBI's misuse of a little-known federal law to imprison him without charges. He was arrested and imprisoned under harsh conditions for more than two weeks—even though the FBI had no probable cause to believe he had done anything wrong. The ACLU represents Mr. al-Kidd in his effort to hold the government accountable for its violation of his rights. Last week, the federal district court in Idaho issued two long-awaited decisions calling the FBI to account for Mr. al-Kidd's unlawful arrest.
