"The three Navy SEALs stomped on the bound Afghan detainees and dropped heavy stones on their chests, the witnesses recalled. They stood on the prisoners’ heads and poured bottles of water on some of their faces in what, to a pair of Army soldiers, appeared to be an improvised form of waterboarding....A United States Army medic standing guard at the base, Specialist David Walker, had expected the men from SEAL Team 2 to put a stop to the abuse. Instead, he said, one of them “jump-kicked this guy kneeling on the ground.” Two others joined in, Specialist Walker and several other soldiers recounted, and along with the Afghan militiamen, they beat the detainees so badly that by dusk, one would die. The four American soldiers working with the SEALs reported the episode, which has not previously been disclosed. In a Navy criminal investigation, two Navy support personnel said they had witnessed some abuse by the SEALs, as did a local police officer. Separately, an Afghan detained with the man who died provided a detailed account of mistreatment by American troops and Afghan militiamen in an interview with The New York Times...Even before the beatings, some of the SEALs had exhibited troubling behavior. According to the soldiers and Afghan villagers, they had amused themselves by tossing grenades over the walls of their base, firing high-caliber weapons at passing vehicles and even aiming slingshots at children, striking them in the face with hard candy."
