Eating during Ramadan is not a sin. You fast to sacrifice and share together (really, in spite of what you heard people get fat during Ramadan). But young children, the elderly, and the sick aren't required to fast nor is it considered a sin not to.

The doctors could have force fed them swine blood at high noon and it would not make an iota of difference. To the detainees it's a bullshit maneuver that says, "see, we're respecting Islam, we aren't burning the Koran anymore," when everyone can clearly see this is utter bullshit.
