They was insane, they do a enormous deserve to islam as religion and faith and , secondarely, to all of religion. They put so much oil in sand and in pilot clothes so at the end, blood really boil inside his body. I not understand why they estinguish the flame and not let it to burn body completely. This care for preserving evidences for self incriminate them is suspicious.

P.S. Old style naked Impaller also work fine
