Yep! That's exactly what I was thinking of.

I've been on the side of disclosing a handful of times and it's a gamble each time whether I'm going to get a CFAA threat (both implicit and explicit threats).

They were using a bit of hyperbole for sure (though another poster accurately pointed out to you methods used against Northern Irish folk), but the reaction of gov agencies to use imprisonment (even as a threat!) for pointing out security fuckups isn't without precedence. It's happened to me :)

So, I guess I really don't understand your point. That being arrested for pointing these things out isn't bad because it's not being disappeared?

I shouldn’t have used the word disappeared, I just meant picked up. And yeah no, not for saying a substation exists and could be bombed.

But for saying there is a single substation that, if taken out (by sabotage, terror attack, arson, or whatever), would cause great embarrassment and economic damage to the country by disabling THE British Airport? I think that’s a whole different matter.
