No intention to spread FUD. And I put very low faith in anything BCX says. But a low probability of something awful, is still worthy of some concern surely. Either the guy is purely malicious, and is spouting what he knows to be nonsense, or he truly believes that he's stumbled onto something, and he doesn't seem to have been convinced by anything anyone else has said that it's nothing. That must leave some small chance that he has really found something. What is the cost to a few checkpoints between now and this time next week, just in case?
There is no evidence of an attack coming, there was threat, but not any evidence. Also interesting... is that the things that have been pointed to as evidence of an attack were obviously not-attacks but were just the sort of thing that might get fud-duds all excited and rumoring into the echo-chamber. I spent some effort to shine the light of knowledge and truth on these until they subsided.
There is much effort expended in "appearing strong" when much less effort could be offered with some simple evidence (if such an attack were actually building). This strongly suggests there is no attack pending.
