According to the Associated Press:
Spokesman P.J. Crowley said Tuesday that Umar Farouk Abdulmutallab's visa was one of several the agency has revoked since the Dec. 25 incident as the result of a review into security procedures ordered by President Barack Obama.
Call me a crazy romantic, but it might have been more helpful to revoke his visa before he tried to blow up an airliner, not 11 days after.
Of course, having revoked his visa, won't ICE now have to deport him? Nah, they couldn't be that obtuse, could they?
