I'm sure the SEC will get a copy of all emails, meeting schedules and chats of that time. If there was any phone call, meeting or email between one of these guys and someone with knowledge of the matter, it will be very hard for them to argue that they didn't know. Even if they weren't told details, they could've seen that the others were obviously dealing with something very serious.
