The people involved in torture were barely convicted if convicted at all, and according to them, instructions and methdology of techniques involving knee strikes, waterboarding, etc. came from the top. And again, Dick Cheney commented that it was not torture. According to Cheney it was "abuse."
This is what Dilawar experienced at Bagram, does it qualify as torture to you?
A black hood pulled over his head
Knee strikes to the abdomen
Peroneal strikes (a nerve behind the kneecap)
Shoved against a wall
Pulled by his beard
His bare feet stepped on
Kicks to the groin
Chained to the ceiling for extended hours
Deprivation of sleep
Slammed his chest into a table front
Specialist Glendale C. Walls of the U.S. Army was the only person convicted of Dilawar's death, and he served two months. Dilawar was beaten to death and his corpse was left chained to the ceiling.
Army Colonel Lawrence Wilkerson, who was appointed chief of staff by Secretary of State Colin Powell in 2002, during George W. Bush’s first administration. Wilkerson told “60 Minutes” that he could “smell” a cover-up and was asked by Powell to investigate how American soldiers had come to use torture and stated; "I was developing the picture as to how this all got started in the first place, and that alarmed me as much as the abuse itself because it looked like authorization for the abuse went to the very top of the United States government". Willie V. Brand, a solider convicted of assault and maiming in two deaths, and Brand’s commanding officer, Capt. Christopher Beiring confirmed that several of their leaders had witnessed and knew about the abuse and torture of the prisoners.
Beiring and Brand showed no remorse when recounting the torture. Beiring was charged with dereliction of duty, a charge that was later dropped. Brand was convicted at his court martial, but rather than the 16 years in prison he was facing from the charges brought against him, he was given a reduction in his rank.
