It is not improbable that a separate charge is lodged against Mark Karpeles and be extradited, being single owner of Mutum Sigillum LLC, based in Delaware.
Isn't Mark attending bitcoin2013 ? It's located in the US, so that would be a good time to arrest him wouldn't it? Not that Japan wouldn't extradite him. But this sounds like a good opportunity to bring him to "justice" quickly.
Yes, but I hope they don't. The law may be the law, and Mt Gox can improve, but he doesn't deserve to be arrested for this.
