FBI haven't found the servers probably, yet. They only got one admin. They'll make him squeal. That's very easy. 2 choices.
1-Alex tells them everything, he stays in jail for the rest of his life.
2-Alex tells them nothing, he still goes to jail but he'll get some extra there;)
It's only a matter of time now.
