I note that in his most recent response (which actually tells us nothing new), Patrick has again neglected to tell us if he has obtained a warrant for his actions and what he is permitted to do. As you should all be able to tell, this is a pretty important area of ambiguity that needs clarification. Please answer the question Patrick.
Patrick acted upon the request of Bitcoinica's creditors. Since Bitcoinica, to our best knowledge, did not file a police report, nor seems to care whether the funds are returned to the creditors or not, it might be possible to argue that the creditors are the legitimate owners.
