Who SABOTAGED the Investigation?

Word was that the younger brother in the Boston bombing was blabbing (as best he could) to FBI questioners until a federal judge showed up and read him his rights just HOURS after formal charges were filed against him. He immediately shut his trap (figuratively). Who sent this judge, and why? He was a recently naturalized citizen and should have NEVER been treated as a citizen. He IS a FOREIGN COMBATANT that was MISTAKENLY made a citizen just before bombing the Boston Marathon and should have been so treated. Do we “give their rights” to combatants captured on the field of battle (which was what the Boston Marathon turned out to be) and should have been treated the same way we treat enemy combatants: that is, sent to GITMO and questioned until he vomits up everything he knows before being “tried” in military court and executed. SOMEBODY in the Obama administration didn’t want him to talk any more and did something about it. We need to know who it was and WHY. I think the order came DIRECTLY from Obama even if that may not be “official.” Whoever “officially” gave that order should be arrested and charged with obstruction of justice. If it was Obama, so be it. (Just common sense)
