Quoth the Fafblog,

in the weeks following September 11th, the United States Constitution was apprehended in Afghanistan and transferred to a military detainment facility in Guantanamo Bay, Cuba. The Medium Lobster cannot divulge further details without compromising America’s intelligence apparatus, but civil libertarians should rest assured that the Pentagon has established the Constitution’s clear ties to al Qaeda, and that it is no accident that America has not been attacked since the deadly document’s capture.

So that’s where it went. I had been wondering.
