Moqtada At The Execution?

Lots of rumors on the internets and from the Saudi daily news, that one of Saddam's hangmen was in fact Moqtada al Sadr.
That would explain the constant chanting of 'Moqtada' thru the video. Moqtada's father was executed by Saddam.

Al Sadr leads a violent Shiite militia that's killed many Sunni civilians, hundreds of Americans including Cindy Sheehan's son and is proof that Maliki controls nothing in Iraq but his own bladder perhaps, but only in the Green Zone.

If true, this will certainly inflame the civil war.
