Suetonius, a biographer of Roman emperors, claimed that the violent ruler Tiberius had a clifftop location in Capri from which he liked to watch his victims thrown into the sea. “A party of marines were stationed below,” Suetonius wrote, “and when the bodies came hurtling down, they whacked at them with oars and boathooks, to make sure that they were completely dead.”

On May 2, 2011, Rear Admiral Charles Gaouette emailed Chairman of the Joint Chiefs of Staff Michael Mullen to report on the traditional Islamic procedures that were followed in the burial of Osama bin Laden. “The deceased’s body was washed (ablution) then placed in a white sheet. The body was placed in a weighted bag. A military officer read prepared religious remarks, which were translated into Arabic by a native speaker. After the words were complete, the body was placed on a prepared flat board, tipped up, whereupon the deceased’s body slid into the sea.”
