In a Minnesota courtroom more than a decade ago, federal prosecutors said Salah Osman Ahmed had helped the US government.
A judge was about to decide the former security guard’s fate, 14 years after he’d immigrated to Minnesota, four years after he’d pleaded guilty to providing material support to terrorists, and seven months after he’d taken the stand as a cooperating witness in a high-profile trial.
On a morning in May 2013, when it was time for a decision in Ahmed’s own case, prosecutors cited his “substantial assistance” and recommended a reduced sentence.
