It is an islamic thing because if the head is buried apart from the body terrible things happen to the soul according to their belief.

The collateral damage has already occurred because once IS takes over an area they kill everyone who will not subscribe to their misbegotten beliefs.

As to your suggestion as far as these misbegotten pigs are concerned I think Drawing and Quartering would be apropos.
