The shooter was obviously a demoniac. Keep in mind that although Judas was an apostle and apparently performed miracles as did the other apostles and disciples whom Jesus sent out, perhaps even expelling demons, ultimately Satan entered into Judas when Christ handed him the morsel, meaning that at that point Judas had no free will. Satan had taken control of his soul. We are going to see this happening more and more. Hence, if the angels do not provide protection it will become quite noticeable. Right now JWs can dismiss it as a one-off thing. Maybe the angels were taking a break or doing something else. But if there is another Kingdom Hall shooting or a similar atrocity then even the hardcore Society men are going to start asking hard questions.
I am blasting out Kingdom Bulletin #24 to the few hundred elders on my contact list. We'll see if they are more respective now than in the past. Sadly, Australia ditched all of the congregation emails they had set up. No doubt orders from the branch to prevent messages from e-watchman getting through.
