I think we can assume the e-mails sent out to at least De La Carrere is real. She would be stupid to forward it to Ortega if she had made this all up herself. As for the purported "big doc leak", there's nothing, nothing at all. It's hard to prove a negative, but most parsimonious assumption is that the leak does not exist. Thus we are left with only two possible scenarios behind the e-mail (or mails, if, ass indicate don ESMB, more have received them): Either OSA/Miscavige believe the leak exists, or they are on a fishing trip throwing shit at the wall to see if anything sticks. Both scenarios smells of incompetence and/or desperation.
