Now it's a news: DOD said they will follow Geneva Convention

I mean, this is really a news, but I don't think it should be. Don't you think they should have followed it anyway?

The Pentagon memo, issued last Friday and released today, orders that all detainees be treated in compliance with what is known as Common Article 3 of the Geneva Conventions, a passage that requires humane treatment and a minimum standard of judicial protections for prisoners.
