First, there's a spoiler here. If you haven't seen The Departed, do not read the rest of this post. It's a fantastic movie. Go see it. Don't let this post spoil it for you.
Remember the final scene? Matt Damon is coming home with groceries. He unlocks the door, walks in. Mark Wahlberg is waiting for him. Watch the scene, below, and remember what Damon says.
That's Obama. He must know this NSA thing isn't done blowing up on him. He's finished. If he weren't President he'd want the guy who is President to expose the whole thing proactively, pardon Snowden, and resign in disgrace.
This has to be vetted. Time to clean up the mess, pay the piper, whatever. We have totally lost our way. This is the last moment we get to turn back and get things right.
