Well, that CT is certainly unfounded but your entitled to your own CT.
The reason I raise the point about the tone of the administration is because there was chatter among intelligence agencies that this administration was cracking down on past decisions, particularly by the CIA, during the last administration. Remember, they pushed hard to release CIA documents and tried to prosecute CIA officials and lawyers.
I'm not saying this had a direct impact on the failure of the intelligence agencies to act and share information appropriately in this case and in the Ft. Hood shooter case, but it is a possibility. In both cases, ample warnings were present and they failed to protect us.
