Libel? Slander? Where's the suit? If this guy actually is Satoshi the last thing in the world he wants is to be on a witness stand.

Opening a case against Newsweek lets them subpoena all sorts of records that they aren't entitled to with out a case, primarily because the truth is a defence to slander / libel, and if this guy loses then he's forever Satoshi.

Also it's going to be pretty difficult to prove that he suffered damages from the article.
