While not the strongest argument (The absence of an argument is not an argument), I do appreciate you bringing up this nuance which I think is a valid one. The FBI's assumption is absolutely newsworthy, and I'm glad Schneier reported it, even though he abdicated any judgement either way. You're correct in saying that he does not elaborate or contridict the FBI statement, but it should also be noted that neither does he endorse it. So I am moving Schneier from the "Having doubts" column over to the "ambivalent" column in my mental list. Thanks for taking the time to provide more information.
