From Politicolive, a quote that will no doubt receive some play today:

DHS Secretary Janet Napolitano said that the thwarting of the attempt to blow up the Amsterdam-Detroit flight this week demonstrated that "the system worked."

Asked by CNN's Candy Crowley on "State of the Union" how that could be possible when the young Nigerian who sought to set off the bomb was able to smuggle explosive liquid onto the flight, Napolitano responded: "We're asking the same questions."

Napolitano added that there was "no suggestion that [the bomber] was improperly screened."
