Also, i don't like the "judge, jury and executioner" approach shown by mtgox.
In what way has mtgox acted as judge, jury or executioner? He came over a heap of stolen money, and blocked the account while the investigation goes on. Would there be any other sensible thing to do? Any other legal options? If mtgox do something illegal here, like releasing the account with stolen funds before the matter is completely resolved, we are all at risk of loosing everything we have on mtgox.
If he has strong , I repeat very strong proof that I am that "thief", so he must go to police and provide that proof to them, and only with police permission he can block money
You can read the proof in this thread. It is damning evidence, and mtgox doesn't need more than that to block your account. In most jurisdictions a bank or exchange has to block the account when stolen money get transferred to it. VISA, MasterCard, PayPal and your bank would do the exact same thing without waiting for the police. They are not allowed to let the thief run away with the stolen money. You claim to have lawyers, but I doubt it.
But his "proof" that I can't remember nick, chanell details, is not any proof, or fact at all, and every court will refuse to accept it as proof.
You may go on forgetting your own name, it doesn't matter. The story doesn't check out anyway. You made it up, and even changed the story when you got more details about your fictional trade, but it doesn't work. The block chain contains the facts.
