I would hesitate to call Strudle a criminal no matter what his relationship and activities with Mt. Gox might be.  It's a small and unregulated dog-eat-dog economy and if someone is expecting to be competitive without employing various forms of favor which would normally be illegal (on paper at least), then they are just to dumb to remain in the game.  And probably won't.

Certain activities occurring inside the Bitcoin ecosystem may eventually filter up to the mainstream court systems, but I'll bet it will be unusual, and the kinds of activities which Strudle/Mt. Gox are theorized to be involved in will not be among them.  My best guess.  At least if they can avoid antagonizing various mainstream law enforcement agencies, and I'm sure that a little data-sharing will smooth any ruffled feathers that might occur in this sphere.
