No, I don't, because Kevin Mitnick wasn't a member of the U.S. military like Manning, and it would be manifestly unconstitutional to transfer a U.S. citizen from U.S. soil into the prison at Guantanamo Bay. The habeas petition to the Supreme Court would take about nine seconds.
If you think the Obama administration no longer feels bound at all by the Constitution even in the face of an explicit ruling from SCOTUS, then, as I said, debating about it on hn will accomplish essentially nothing: We're already way too far down the slope. You apparently think that's the case, but that should be a fringe position in any community I'd like to participate in. Sadly it seems it's not.
