On Friday morning in downtown Manhattan, Osama bin Laden’s son-in-law appeared in a federal courtroom to be charged with conspiring to kill Americans. In a sober, orderly proceeding that lasted a total of 17 minutes, Judge Lewis Kaplan explained to Suleiman Abu Ghaith his rights, appointed his defense lawyers, read the charges against him, recorded his plea of “not guilty,” ordered the prisoner’s continued detention and announced that he would set a trial date for the case in 30 days.
