If these are just "innocent civilians," why do some of them have aliases?
Standards for transliterating Arabic script into the Roman alphabet are not universal (for example, Khadafy/Khadaffi/Qadafi, Osama/Usama). Different translators use different standards, mostly depending on where they studied Arabic. If more than one translator worked on the documents, then they probably generated more than one transliteration of the decedent's name.
Thats a good question! I want to hear details on this, I bet these folks are the "innocent civilians" we hear about.
