Torture offers no assurances of achieving the truth, even in a ticking-bomb scenario. Therefore, to call it a "safeguard" is false advertising.
A second major problem with this technique is that evidence gained from it is unreliable. ... This unfortunately has happened and we have had problems ranging from agents chasing false leads to the disastrous case of Ibn Sheikh al-Libby who gave false information on Iraq, al Qaeda, and WMD.
More on the deferred costs of the Bush-Cheney feel-good era on National Security:
A fourth problem with this technique is that ignores the end game. In our country we have due process, which requires evidence to be collected in a certain way. The CIA, because of the sensitivity of its operations, by necessity, operates secretly. These two factors mean that by putting the CIA in charge of interrogations, either secrecy is sacrificed for justice and the CIA's operations are hampered, or justice is not served. Neither is a desirable outcome.
