The Evidence on "Inhanced Interrogation"

It has been in the news for a while about the enhanced interrogation, basically a light word for water boarding and sleep deprivation. Bush and his crew have been accused of using torture to get information from their prisoners, which of course, is illegal. However, Bush has admitted that they have interrogated, but have done nothing to shock the conscience. The question is if simulating drowning really is a shocker, to me it is. When asked for security tapes, they somehow were destroyed by the CIA, a real coincidence. Now though, Bush has enabled for Congress to receive some testimony and evidence of the interrogation of two prisoners. I believe that this new information really wont be that much help to discover the truth. Bush will only give enough to make it seem that they have not done anything bad, when they probably have because the disappearing video tapes and other evidence is just stupid. If our own CIA cannot hold onto a couple of tapes, then how are they supposed to find Osama or other terrorists, they definitely are not as good as we though, or, their just covering it up. Basically, Bush is just trying to cover, he knows just saying it doesn't happen wont do enough, so hes going to release some info, but its going to be so censored it will not be able to prove enough.
