According to the sources, only a handful of CIA interrogators are trained and authorized to use the techniques:

1. The Attention Grab: The interrogator forcefully grabs the shirt front of the prisoner and shakes him.

2. Attention Slap: An open-handed slap aimed at causing pain and triggering fear.

3. The Belly Slap: A hard open-handed slap to the stomach. The aim is to cause pain, but not internal injury. Doctors consulted advised against using a punch, which could cause lasting internal damage.

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 near 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.

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.

[a]fter sufficient dilation the surgical operation can commence. The woman is placed under general anesthesia or conscious sedation. The doctor, often guided by ultrasound, inserts grasping forceps through the woman's cervix and into the uterus to grab the fetus. The doctor grips a fetal part with the forceps and pulls it back through the cervix and vagina, continuing to pull even after meeting resistance from the cervix. The friction causes the fetus to tear apart. For example, a leg might be ripped off the fetus as it is pulled through the cervix and out of the woman. The process of evacuating the fetus piece by piece continues until it has been completely removed. A doctor may make 10 to 15 passes with the forceps to evacuate the fetus in its entirety, though sometimes removal is completed with fewer passes. Once the fetus has been evacuated, the placenta and any remaining fetal material are suctioned or scraped out of the uterus. The doctor examines the different parts to ensure the entire fetal body has been removed.

the doctor extracts the fetus in a way conducive to pulling out its entire body, instead of ripping it apart. One doctor, for example, testified: "If I know I have good dilation and I reach in and the fetus starts to come out and I think I can accomplish it, the abortion with an intact delivery, then I use my forceps a little bit differently. I don't close them quite so much, and I just gently draw the tissue out attempting to have an intact delivery, if possible."... Rotating the fetus as it is being pulled decreases the odds of dismemberment.... A doctor also "may use forceps to grasp a fetal part, pull it down, and re-grasp the fetus at a higher level—sometimes using both his hand and a forceps—to exert traction to retrieve the fetus intact until the head is lodged in the [cervix]."...

In the usual intact D&E the fetus' head lodges in the cervix, and dilation is insufficient to allow it to pass.... [Dr. Martin] Haskell explained the next step as follows:

At this point, the right-handed surgeon slides the fingers of the left [hand] along the back of the fetus and "hooks" the shoulders of the fetus with the index and ring fingers (palm down). While maintaining this tension, lifting the cervix and applying traction to the shoulders with the fingers of the left hand, the surgeon takes a pair of blunt curved Metzenbaum scissors in the right hand. He carefully advances the tip, curved down, along the spine and under his middle finger until he feels it contact the base of the skull under the tip of his middle finger. [T]he surgeon then forces the scissors into the base of the skull or into the foramen magnum. Having safely entered the skull, he spreads the scissors to enlarge the opening. The surgeon removes the scissors and introduces a suction catheter into this hole and evacuates the skull contents. With the catheter still in place, he applies traction to the fetus, removing it completely from the patient....

This is an abortion doctor's clinical description. Here is another description from a nurse who witnessed the same method performed on a 26-week fetus and who testified before the Senate Judiciary Committee:

Dr. Haskell went in with forceps and grabbed the baby's legs and pulled them down into the birth canal. Then he delivered the baby's body and the arms—everything but the head. The doctor kept the head right inside the uterus... The baby's little fingers were clasping and unclasping, and his little feet were kicking. Then the doctor stuck the scissors in the back of his head, and the baby's arms jerked out, like a startle reaction, like a flinch, like a baby does when he thinks he is going to fall. The doctor opened up the scissors, stuck a high-powered suction tube into the opening, and sucked the baby's brains out. Now the baby went completely limp... He cut the umbilical cord and delivered the placenta. He threw the baby in a pan, along with the placenta and the instruments he had just used....

Dr. Haskell's approach is not the only method of killing the fetus once its head lodges in the cervix, and "the process has evolved" since his presentation.... Another doctor, for example, squeezes the skull after it has been pierced "so that enough brain tissue exudes to allow the head to pass through." ... Still other physicians reach into the cervix with their forceps and crush the fetus' skull.... Others continue to pull the fetus out of the woman until it disarticulates at the neck, in effect decapitating it. These doctors then grasp the head with forceps, crush it, and remove it.... Some doctors performing an intact D&E attempt to remove the fetus without collapsing the skull.... Yet one doctor would not allow delivery of a live fetus younger than 24 weeks because "the objective of [his] procedure is to perform an abortion," not a birth.... The doctor thus answered in the affirmative when asked whether he would "hold the fetus' head on the internal side of the [cervix] in order to collapse the skull" and kill the fetus before it is born.... Another doctor testified he crushes a fetus' skull not only to reduce its size but also to ensure the fetus is dead before it is removed. For the staff to have to deal with a fetus that has "some viability to it, some movement of limbs," according to this doctor, "[is] always a difficult situation."
