We will join any organized legal action against Mr. Seale in the United States, where I think there's a good chance of holding him personally accountable for stealing our money, given the trail of public claims to his ownership of Bitcoinica and his direct access to their USD accounts. Finally, we encourage anyone in Washington State who was harmed in Bitcoinica's theft to file in small claims court against Mr. Seale, which is the easiest way to put his involvement in the public record.
Based on on the publicly available in formation that came out during the last two weeks, my personal opinion is that Tihan was not actually supposed to have access to anything, and that (contrary to my original assumption) the reason why the password for LastPass he used was not changed lies with Bitcoinica Consultancy rather than Tihan. I still think that incompetence on part of Bitcoinica Consultancy is the most plausible explanation. In that case, Tihan and Zhou are harmed just like we (the depositors) are, and it is in their interest to cooperate with us.
Edit: another harmed party and a potential ally is Christopher Heaslip, who is still listed as a director of Bitcoinica Consultancy at the New Zealand Company Registry, even though the leaked documents show that BC was taken over by Amir, Patrick and Donald. The NZCR website says that the records needs to be updated within 20 working days of the change, but this didn't happen.
