Oh, but I see, it isn't the FBI interview that they suppressed that matters - only the brief soundbite pumped out by CNN.
From Newsweek:
Walker, who suffered a gunshot wound, starvation and near-drowning when the basement of the fortress was flooded, was one of about 80 Taliban supporters to survive a vicious, weeklong battle that left a CIA agent and hundreds of foreign fighters dead. Shortly after his capture last weekend, Walker identified himself as an American citizen and told a NEWSWEEK reporter that he had come to Afghanistan to help the Taliban build a “pure Islamic state.” In a subsequent interview with CNN from his hospital bed, Walker described himself as a “jihadi”, a fighter of holy wars, and said that he had received combat training at a camp in Afghanistan where Osama bin Laden appeared several times. Before joining the war in Afghanistan, Walker said he had fought alongside Pakistani forces in Kashmir, the disputed region between India and Pakistan. According to Northern Alliance sources, he has now been taken into custody by soldiers from the U.S. Special Forces
Go ahead; keep defending him, but do NOT bother quoting the United States Constitution to us.
*sigh* Try to keep up; no evidence has been ruled in or out yet.
