EL RENO, Okla. — They opened the door to Cell 123, and President Obama stared inside. In the space of 9 feet by 10 feet, he saw three bunks, a toilet with no seat, a night table with books, a small sink, prison clothes on a hook, some metal cabinets and the life he might have had. In becoming the first occupant of his high office to visit a federal correctional facility, Mr. Obama could not help reflecting on what might have been. After all, as a young man, he smoked marijuana and tried cocaine. But he did not end up with a prison term lasting decades like some of the men who have occupied Cell 123.
