4. Long Time Standing: This technique is described as among the most effective. Prisoners are forced to stand, handcuffed and with their feet shackled to an eye bolt in the floor for more than 40 hours. Exhaustion and sleep deprivation are effective in yielding confessions.

5. The Cold Cell: The prisoner is left to stand naked in a cell kept ear 50 degrees. Throughout the time in the cell the prisoner is doused with cold water.

6. Water Boarding: The prisoner is bound to an inclined board, feet raised and head slightly below the feet. Cellophane is wrapped over the prisoner's face and water is poured over him. Unavoidably, the gag reflex kicks in and a terrifying fear of drowning leads to almost instant pleas to bring the treatment to a halt.

Let's take waterboarding:

According to the sources, CIA officers who subjected themselves to the water boarding technique lasted an average of 14 seconds before caving in. They said al Qaeda's toughest prisoner, Khalid Sheik Mohammed, won the admiration of interrogators when he was able to last between two and two-and-a-half minutes before begging to confess.

"The person believes they are being killed, and as such, it really amounts to a mock execution, which is illegal under international law," said John Sifton of Human Rights Watch.

You don't need to be a rocket scientist to know that torture leads to questionable confessions. In the case of the detainees, the U.S. may have taken action based upon the faulty information:

According to CIA sources, Ibn al Shaykh al Libbi, after two weeks of enhanced interrogation, made statements that were designed to tell the interrogators what they wanted to hear. Sources say Al Libbi had been subjected to each of the progressively harsher techniques in turn and finally broke after being water boarded and then left to stand naked in his cold cell overnight where he was doused with cold water at regular intervals.

His statements became part of the basis for the Bush administration claims that Iraq trained al Qaeda members to use biochemical weapons. Sources tell ABC that it was later established that al Libbi had no knowledge of such training or weapons and fabricated the statements because he was terrified of further harsh treatment.

The CIA officers don't fault Libbi, they fault the torturing agents:

However, sources said, al Libbi does not appear to have sought to intentionally misinform investigators, as at least one account has stated. The distinction in this murky world is nonetheless an important one. Al Libbi sought to please his investigators, not lead them down a false path, two sources with firsthand knowledge of the statements said.

Where are they being held?

sources say, there are a very limited number of these locations in use at any time, and most often they consist of a secure building on an existing or former military base. In addition, they say, the prisoners usually are not scattered but travel together to these locations, so that information can be extracted from one and compared with others. Currently, it is believed that one or more former Soviet bloc air bases and military installations are the Eastern European location of the top suspects. Khalid Sheik Mohammed is among the suspects detained there, sources said.

Only agents specificially trained in the torture techniques are supposed to appply them. On one particular day, a newbe agent got the gritty job. It ended with the death of the detainee:

a young, untrained junior officer caused the death of one detainee at a mud fort dubbed the "salt pit" that is used as a prison. They say the death occurred when the prisoner was left to stand naked throughout the harsh Afghanistan night after being doused with cold water. He died, they say, of hypothermia.

His wasn't the only death:

According to the sources, a second CIA detainee died in Iraq and a third detainee died following harsh interrogation by Department of Defense personnel and contractors in Iraq. CIA sources said that in the DOD case, the interrogation was harsh, but did not involve the CIA.

Go read the whole thing, and then read how the Iraqi's are doing the same thing over there. It's like nothing has changed.
