I want to clarify something I said in my OP when I said I hope the KH burns down. I meant that if hundreds of homes and businesses are on fire then I see no reason why the KH should be spared.
If the Hall hadn't burned the JW's would have spun it as proof that Jehovah's hand was involved and it was an "act of God" that spared them.
Thankfully l'm sure they had fire insurance but come to think of it there may not be coverage for this disaster because ironically forest fires may be considered an "act of God" as well
