After the Abu Ghraib incident, in early 2004, then Colonel Quantock was called in as commander of the 16th Military Police Brigade to relieve the 800th Military Police Brigade. Quantock relieved Brigadier General Janis Karpinski on 14 January 2004, and was given responsibility to break down and rebuild the Abu Ghraib prison during the sensitive media frenzy that followed the revelations of abuse by members of the 800th.
