> someone shared something incriminating in a group chat and got arrested, and that info was only shared in the group chat

“Only” is doing an incredible amount of work there.

Unless you concoct something incriminating solely for the purpose of testing this, the something incriminating being discussed in group chat previously happened in the real world. Ripples of information were created there and can be found (parallel construction).

Right, but parallel construction only works if opsec fails. Good luck with repeating that feat forever. You clearly have far more faith in the FBI than I do. Now repeat this feat for every dumbass in intelligence in every country.

My position doesn’t require a lot of faith in the FBI.

If they fail in parallel construction, they always have the option to continue. For the vast majority of cases where opsec isn't 100% foolproof, we hear about them. For the few cases where it was foolproof, we just don't hear about them.

		It requires faith that they prioritize keeping such abilities a secret rather than prosecuting, and again, I do not share this faith.
