Murdoc has the details on the conviction of Chi Mak. He even taunts one commenter who seemed to be taking the spy's side a while ago (said commenter deserved to be taunted). Murdoc's post back at the time of the arrest has a rough idea of what Mak did for China. One part of the case for reactivating the Iowa-class battleships is summed up in that post.
Seriously, though, this was good work by our counter-intelligence community. Hopefully, we will be able to deter the next spy.
