If you’re in charge of tracking Islamic terrorists, and the Islamic terrorists have a big web site or Facebook page boasting about their plans and successes - it’s your duty to look at it.

Riiiight...the CIA is looking for "Islamic terrorists" - you know, the kind of people who go to church on Sunday, belong to the NRA, take the Constitution at face value, kvetch about the Federal Reserve, and grow their own food.
The Nazis took over the OSS when it became the CIA and have been in bed with their natural allies, the muzzies, ever since.
