Interesting that the lead study author Caroline Arcini states that"shaming of the dead is most likely a deep rooted behavior in humankind."It mentions the practice occurring up into the first World War.Most likely with prisoners I would imagine?Information of this sort fascinates me.The why we are and the way we are and how many things are the same all over the world.
