What I see in the video Irenic linked to is first video of the coffins being moved into the hanger and saluted by military personnel,and then still shots, with the words of a Muslim prayer superimposed over the stills, and what I hear is presumably that prayer being sung in Arabic.
But I do not see any video of a Muslim cleric in that hanger, in uniform or in religious garb, singing that prayer.
The video Irenic linked to is over three hours long. Where is the video or stills of the cleric in the hanger, or testimony from witnesses who were there, who say, yes there was a Muslim singing a prayer, and saying who recorded it?
The Western instrumental music in the early, moving part of the hanger video was edited in and replaced the original sound. The sung prayer could have been edited in as easily.
I am not saying I disbelieve these allegations, but the hanger video is no proof at all, and I do not have three hours to watch a press conference trying to find the hanger witnesses.
