The diary is a fascinating read - not least because it documents the fact that as of last Sunday, one of the private contractors identified in the Army's own internal investigation of the torture scandal was still at Abu Ghraib, and may still have been supervising or conducting interrogations.

The contactor's name is Steven Stephanowicz, and he works for CACI International - one of two firms that have been publically linked to the abuses in Abu Ghraib's high-security cell block.
