Yes, it is a 'so what.' But a still image uploaded with an audio file means nothing.
Also, a thin paperback book in a mans back pocket wouldn't draw any more attention than his wallet.
I find it interesting that the man pictured is wearing what would be considered what a witness would never wear as being overly casual and sloppy, not even to visit a Bethel room or walk in the neighborhood. Why, the man with the demonic goatee is dressed in an appropriate casual polo shirt.
