Are you? Yeah there is strong evidence that he did that and it's very likely he'll be found guilty. But after he lost his freedom and access to computers with classified documents and was imprisoned, how exactly could he be a security threat whether or not he was in isolation or not. They revoked his clearance and I seriously doubt he has knowledge of secrets other than what was smuggled off the the computer and they obviously invalidated the password(s) that he knew. So how would he be a threat?
