That is the problem Moose, the tale has never been told.
The murderers and the Church kept it secret and hidden for as long as possible, they were silent for three years. When the story came out, the Church blamed one man. Twenty years later, he alone took the blame. He was a scapegoat - number 4 in command. That means he received orders from one or more of his superiors.
Do you honestly think one lone man ran around and shot over 120 people point blank in the head?
How true. Will the truth ever be told ? I don't think so. The story will will add more fictions every time it's told and many will say this fiction is true. Very sad.
Chuck Norris could do it.
