That's the $64k dollar question. They're worse than CNN ever thought about being and being such Jihads-on-the-spot it seems they're not just breaking the news but *making* the news. Does it surprise anyone they have this tape to add to their ever growing collection of beheadings?
I wouldn't be surprised if they've had the tape awhile. Since the turn over came early, there were no beheadings scheduled. I'd bet they kept this back for just such an occasion.
Imagine that there was news bureau during WWII which had free reign to go anywhere and spread Nazi propaganda while we could do nothing about it because they we an accredited "news" organization. That's Al-Jazeera. This insane political correctness is the real killer. However, nothing will be done about it, I guess, until tens of thousands of Americans lay dead in their homes and on the streets of America.
