"The attackers probably produced the missile weapons through digestive processes."
Their own? They dropped trou, stood there and took a dump, into their own hands, with the express purpose of slinging it at this kid? Good grief, it's some sort of scatalogical "Lord Of The Flies."
It IS Lord of the Flies. I bet it happens in prisons all the time?????
According to coppers I know, many home invaders and burglars leave sphincter souvenirs at the scenes of their crimes. A form of humiliation for the victim. This sounds like a vile variation of a familiar theme.
