Yes. If a big market one expects to be under attack reports fending off attack, then one would be more optimistic about it:
Hence, observing BMR silence pushed the infiltration outcome to a high posterior while the not-trying remained still pretty unlikely. Of course, for an obscure small marketplace, the reasoning would happen the other way around: because it starts off more likely to be ignored than infiltrated, silence is golden
(That said, that only applies to the one particular kind of observation/argument from silence; as I told Chen, there were several reasons to expect BMR to be short-lived on top of the general short-livedness of black-markets, but I think the logic behind those other reasons doesn’t need to be explained since they’re not tricky or counterintuitive like the argument from silence.)
Then it seems to me that when responding to “Surely if BMR had claimed to be seeing law enforcement infiltration I would consider that evidence for infiltration, so how could I turn around and argue that lack of BMR claims was also evidence for infiltration?”, you should lead off with “I would consider that evidence for infiltration, but against an imminent bust”, before launching into all the explanation. That way, it would more clear whether you are denying the premise (“you’d consider that evidence for your thesis, too”), rather than just the conclusion. And the phrase “If a big market one expects” would a lot clearer with “that” between “market” and “one”.
