LN's cannot accept the fact there was a hole in the back of his head. My opinion is the autopsy photo showing the back intact was taken after the procedure when the scalp was sutured shut.
How many bad guys do you figure were involved, altogether, in the planning, the "patsy-ing," the shooting, the getting-away, the planting of false evidence, the altering of photos / films / x-rays, and the all-important (and ongoing!) coverup?
Just a few, or oodles and gobs?
