IIRC, there was a report within days that stated the first people on the scene were wearing protective gear, and removed bodies from the wreck that were also wearing protective gear. They were also said to have removed "equipment".
Yes, one of the articles I just read said that the bodies were removed surreptitiously when a Syrian relief effort was allowed into the area.
Sorry I'm just now bringing this up, but I'm digging around looking for solid mention of ties between all our enemies. An expansion on the Axis of Evil, if you will.
