Step 1: Obama "closes" the Guantanamo detention facility now holding "the worst of the worst" enemy combatants by transferring them to federal prisons (from Club Feds to hard-core lockups) on the American mainland.
Step 2: They will be entitled to the full deck of Bill of Rights constitutional protections, including but not limited to those in the Fifth, Sixth, and Eighth Amendments: Indictment, Double Jeopardy, Self Incrimination, Due Process, Speedy and Public Trial, Confrontation by Witnesses, Counsel, Cruel and Unusual Punishment. And, of course, habeas corpus.
Step 3: Counsel, provided by the far, far American-hating Left, will begin the endless litigation it specializes in (e.g., capital punishment).
Step 4: Some will seek bail, under the Eighth Amendment.
And the Guantanamo part of Obama's transformation of the United States of America will continue long after he is gone.
