because it is normal behaviour by the Arabs. It was expected and accepted that Israeli prisoners will be tortured and murdered. Soldiers who participated in the war knew about it and discussed it among family and friends as routine Arab behaviour. It was not a failure of Israeli PR not to advertise it. Israel just assumes that the rest of the world also knows and understands that this is normal Arab behaviour. What is there to advertise? That which is universally known?
