Does It Matter If Bush Didn't Legally OK Torture?

There are still many folks out there that don't believe that Bush's "enhanced interrogation techniques" constitute torture. For the sake of argument, what do the Geneva Conventions say about acts of inhuman treatment that do not rise to the level of torture?

Article 16

1. Each State Party shall undertake to prevent in any territory under its jurisdiction other acts of cruel, inhuman or degrading treatment or punishment which do not amount to torture as defined in article I, when such acts are committed by or at the instigation of or with the consent or acquiescence of a public official or other person acting in an official capacity.
