Those in hiding had a lot of time on their hands so they made videos of this holy warrier. Now that he’s “sleeping with the fishes” the wives and children at least have video albums of him (if the CIA returns copies for the family).
I highly doubt that this video was taken from the inside, if you know what I mean. The camera turns, so it was nor surveillance. It is very unlikely that of all videos to have taken, they chose one of him watching himself on TV. What is likely, is, knowing that the CIA had a nearby house, they took this video using some advanced technology, like zeroing in on small reflections from object near a window they had access to. Perhaps they even had a tiny camera mounted on a remote control bug, which I do know has been entertained.
