the unfortunate reality is that the CIA has been using torture tactics for decades. this did not start under Bush, it was just legalized and expanded under Bush.... and has, as of yet, still remained to be stricken from law under the Obama administration.
See: The Military Commissions Act of 2006 - this made torture legal, of both foreign designates but also of US citizens. Once either the President or Secretary of Defense declares any person, in the United States or of foreign citizenship, an "Enemy Combatant" - they are stripped of all human rights and legal protections - and for the US citizens, they are stripped of citizenship, so that politicians who voted for the bill, as in, almost all of them... could say "this does not affect US citizens" - because once it affects you, you are no longer a citizen. These are very clever lawyers writing these things.
Obama actually voted for this bill as well, and has yet to repeal it. Don't hold your breath.

Here is a copy of the law, along with Congressional discussion following, with certain Congress members speaking out on what the ramifications of this legislation are:http://www.fas.org/irp/congress/2006_cr/h092706.html
Glenn Greenwald, former civil rights litigator and constitutional lawyer, writes on how the law allows for the "legalization of torture and permanent detention":http://glenngreenwald.blogspot.com/2006/09/legalization-of-torture-an_115945829460324274.html
Bill Goodman, legal director of the Center for Constitutional Rights, writes that the MCA that the definition for "enemy combatant" is so broad that "t could be read to include anyone who has donated money to a charity for orphans in Afghanistan that turns out to have some connection to the Taliban or a person organizing an anti-war protest in Washington, D.C. The second definition could supersede the first entirely, granting the President shockingly wide latitude to declare anyone a UEC [unlawful enemy combatant]"http://jurist.law.pitt.edu/hotline/2006/10/challenging-military-commissions-act.php
But, this should come as no surprise. The US, largely through the CIA, has supported and helped foreign dictators come to power, and has often created, helped manage, and advise these foreign intelligence agencies and secret police services of foreign despots that commit torture. Just take a look at two brief examples among many - the Shah of Iran and the SAVAK police force, as well as Pinochet and his secret police.
This is simply continuity in empire. Nothing new... and it doesnt look to be leaving anytime soon, either.
