Duh! They want to KILL US????

This is something observant objective people have known for quite some time. Apparently not the Enlightened One, now that he's figure out it might have a "political" cost. NY Post:

So what does this startling policy shift mean for you?

First, the administration has plainly realized that the terror danger is much higher than it believed one week ago.

Second, it means that Shahzad really has been talking -- almost certainly tipping us that there are more America-bound terror trainees out there (or already here) and letting us fit together important pieces of the intelligence puzzle.

Third, the White House obviously fears more terror attacks sooner rather than later.

This sudden policy shift and media mobilization by an administration that's usually lethargic on security issues means that folks at the top are worried about the political costs of a successful terrorist strike.
