This absurdity renders hollow Obama's declaration that "we will not rest until we find all who were involved." Once we've given Abdulmutallab the right to remain silent, we have gratuitously forfeited our right to find out from him precisely who else was involved, namely those who trained, instructed, armed and sent him.
This is all quite mad even in Obama's terms. He sends 30,000 troops to fight terror overseas, yet if any terrorists come to attack us here, they are magically transformed from enemy into defendant.
The logic is perverse. If we find Abdulmutallab in an al-Qaeda training camp in Yemen, where he is merely preparing for a terror attack, we snuff him out with a Predator -- no judge, no jury, no qualms. But if we catch him in the United States in the very act of mass murder, he instantly acquires protection not just from execution by drone but even from interrogation.
