By what right, the former interrogator asks, does one derive the authority to question prisoners as part of a military occupation?
It's an important question to ask and timely too given the steady growth in the number of Iraqi prisoners in US custody over the course of its occupation of Iraq. Pentagon statistics show the US military now holds over 24,000 "security detainees" in Iraq – more than double the number incarcerated by Coalition at the time of the Abu Ghraib prison scandal four and a half years ago.
US forces are holding nearly all of these persons indefinitely, without an arrest warrant, without charge, and with no right to any type of open legal proceedings. It's perhaps a mark of the failure of the United States' political and religious establishments that it falls to a US Army Specialist like Joshua Casteel to wrestle with the moral difficulties of these massive imprisonments. "Letters from Abu Ghraib" shows how the ethical failures of their leaders affect soldiers on the ground.
