This is normal for the régime forces in Syria. Patrick Cockburn was trying to make the opposite point recently, as there is the fog of war we can't really know what to believe.* That's convenient when you are trying to explain away the systematic brutality from one side.
*"A correspondent in south-east Turkey recently visited a Syrian refugee camp where he found ten-year-old children watching a YouTube clip of two men being executed with a chainsaw. The commentary claimed that the victims were Syrian Sunnis and the killers were Alawites: in fact the film was from Mexico and the murders had been carried out by a drug lord to intimidate his rivals."[http://www.lrb.co.uk/v35/n19/patrick-cockburn/diary]
