By May 2003, international work began on the already looted museum but not on other sites.[26] The US military conducted a raid in May on Umma where they found hundreds of trenches with many looters all over the site.[27] On May 7, the Bush Administration replaced Gen. Jay Garner with L. Paul Bremer who was given more power and banned high-ranking Ba'ath Party members from government jobs and disbanded the remains of the Iraqi army.[28] Any guards at archeological sites were unpaid for months and they were not allowed to carry guns.[28] Now, instead of dealing with civilian looters, these unarmed guards were dealing with large mobs of armed people.[28]
