Cooks and Truck Drivers as Iraqi Interrogators

From the UK's ">Guardian yesterday:

Many of the prisoners abused at the Abu Ghraib prison were innocent Iraqis picked up at random by US troops, and incarcerated by under-qualified intelligence officers, a former US interrogator from the notorious jail told the Guardian.
Torin Nelson, who served as a military intelligence officer at Guantánamo Bay before moving to Abu Ghraib as a private contractor last year, blamed the abuses on a failure of command in US military intelligence and an over-reliance on private firms. He alleged that those companies were so anxious to meet the demand for their services that they sent "cooks and truck drivers" to work as interrogators.

Can you fathom this? I can't.
