In fact, I'm not entirely sure I'd be opposed to co-habituating with him, as long as he worked and paid his fair share of the rent.
On that note, I propose an experiment: should any Guantanamo detainees be released, I will invite them to live here with me provided that the United States government finds the idea agreeable. I shall record what happens after; it seems an interesting idea to me.
Khalid Sheikh Mohammed, Abu Zubaydah, and Abd al-Rahim al-Nashiri all seem like deadbeats to me. They might not take kindly to your militant atheism either.
They are also not typical Guantanamo detainees.
They have spent less than half their time in US custody in Guantanamo. Anyways they're not about to be released anytime soon. They'll be tried (and sentenced - though a cloud will always remain over the verdicts, whatever they will turn out to be). Most Gitmo detainees won't be as they did nothing to try them for.
