O.K., I lied about never posting here again. At least this is not repeating myself. From the Guardian:

The loose control of the 20,000-plus private-enterprise soldiers in
                                  Iraq has been thrown into painful relief by the accusations that
                                  hired civilian interrogators and translators encouraged obscene
                                  tortures at Abu Ghraib prison and that one even allegedly raped
                                  an Iraqi boy in his cell.

                                  No senator or congressman appears to have had the least idea
                                  until the scandal broke that the drive to privatise the military had
                                  gone so far as to use civilian contractors for such sensitive jobs.

                                  Aides to Democrat congressman Ike Skelton were particularly
                                  incensed with a reply by Mr Rumsfeld to a demand last month
                                  for information about private mil itary firms in Iraq. Mr Rumsfeld
                                  produced a list of 60 companies, half a dozen of them British,
                                  but withheld all mention of two of the biggest and
                                  best-connected recruiting firms alleged to be at the centre of the
                                  torture scandal - CACI in Washington and Titan in San Diego,
                                  California.
