I think we need to protect the identity of the arsonist so that we don't make Jehovah look bad.
Isn't that how the song goes?
...and if Jehovah has not struck the arsonist with Divine Justice within a period of seven years, isn't that a sign that Jehovah has forgiven him? (I say "him" only because statistically arsonist are more likely to be former Boy Scouts who grew too attached to their Campfire Merit Badges. For all I know the arsonist could be a woman or a pangolin who self-identifies as an emu. I'm not here to judge.)
Leave it in Jehovah's hands, I say! Keep the secular authorities OUT OF IT.
Hey Bud, got a light?
