A military jury gave Osama bin Laden's driver a stunningly lenient sentence on Thursday, making him eligible for release in just five months despite the prosecutors' request for a sentence tough enough to frighten terrorists around the globe. Salim Hamdan's sentence of 5 1/2 years, including five years and a month already served at Guantanamo Bay, fell far short of the 30 years to life that prosecutors wanted. It now goes for mandatory review to a Pentagon official who can shorten the sentence but not extend it. It remains unclear what will happen to Hamdan once his sentence is served, since the US military has said it won't release anyone who still represents a threat. The judge, Navy Capt. Keith Allred, said Hamdan would likely be eligible for the same administrative review process as other prisoners. Hamdan thanked the jurors for the sentence and repeated his apology for having served bin Laden.
