Immigration and Customs Enforcement (ICE), Office of Professional Responsibility, Investigative offices accurately maintained equipment records and complied with vehicle and availability pay requirements. Offices were also accurate in accounting for all firearms. Investigative staff were diligent in complying with the DHS Management Directive relating to the referral of allegations. However, we noted deficiencies in compliance with evidence inventory requirements, and observed inaccuracies in ammunition records. We also found a systemic absence of training on certain firearms and problems with the timeliness of submitting investigative reports. Finally, we found that supervisors did not always review cases on a quarterly basis.
