The interrogation and detention regime implemented by the US resulted in the deaths of over 100 detainees in US custody ? at least [see "Command?s Responsibility," a Human Rights First report from 2006, PDF]. While some of those deaths were the result of "rogue" interrogators and agents, many were caused by the methods authorized at the highest levels of the Bush White House, including extreme stress positions, hypothermia, sleep deprivation and others. Aside from the fact that they cause immense pain, that?s one reason we?ve always considered those tactics to be "torture" when used by others ? because they inflict serious harm, and can even kill people. Those arguing against investigations and prosecutions ? that we "Look to the Future, not the Past" ? are thus literally advocating that numerous people get away with murder.
