There's a line where interrogation techniques become torture, and everybody probably draws that line at another distance...

There's a war going on, and in times of war, different rules apply then in times of peace. It might not make sense to have rules in times of war, but there are rules regardless (as defined by the Geneva Conventions). The US signed those laws, and should apply them. Action has been taken against the people involved, and as far as I'm concerned: case closed.

Of course it sucks that the US are fighting a war against a regime that never signed those laws. Bummer. The US is the bigger person in this case: they could just have said "There's a war going on... they don't follow the rules, we won't follow them either", but instead the government stood up and punished the ones involved. If it would've been the other way around (Iraqi's torturing Americans), they probably would have gotten away with it. If the US would capture them, they'd show they're the bigger person again by giving those people a fair trial.

I'll have to stop now before people start thinking I'm pro-government
