Many reports about the war in Syria frequently quote the „Violations Documentation Center“ (VDC), however the information released by the VDC must be treated with much skepticism.

Here some reasons why:

1.
„This source is highly partisan. For example they divide fatalities into two overall groups: “Martyrs” and “Regime Fatalities”.

“Martyrs” include ISIS fighters and foreign mercenaries killed by the Syrian Army/Militia or even by the U.S. airstrikes around Kobani. See the VDC screenshot photo 1 showing the ISIS “martyr” killed in Kobani. Photo 2 shows a young girl listed as “regime fatality”…There is little or no evidence provided regarding most of the alleged victims. Photographs and video evidence is provided for a small minority of the cases.“

2.
„there are good reasons to believe the VDC is listing dead insurgents as civilians, as well as mislabeling dead government soldiers as FSA fighters.”

One example he cited was the listing of a Jaysh al-Islam militant, ‘Hisham Al-Sheikh Bakri’, killed by the SAA in Douma (infested with Jaysh al-Islam terrorists), in February 2015, which al-Masdar News reported. The VDC also listed ‘Hisham Abd al-Aziz al-Shaikh Bakri’, “however this one is listed as an adult male civilian and not a Jaish Al-Islam fighter,”

If you go to the VDC site and check for adult male civilian deaths it shows (Feb. 16th, 2018) 79.254 deaths, while the total number of civilian deaths is shown as 111.803. So, almost 71% of all civilian deaths are adult males, while we have been hearing that most civilian victims (of course almost all killed by „the regime“) are women, children and elderly…Why is the percentage of adult males so high? Can it be that a sizable portion were NOT civilians?
