Of the opinions particularly relevant to criminal justice policy, the Office of Legal Counsel addressed the authority of the Inspector General to conduct regulatory investigations, the authority of the State Department to issue U.S. passports to aliens to facilitate U.S. law enforcement and intelligence operations, and congressional request for information from inspectors general concerning open criminal investigations. Other criminal justice issues pertain to the use of the National Guard to support drug interdiction in the District of Columbia, the authority of the FBI to conduct background investigations for Congress, legal authority for Customs Service's Operation PALADIN, and the authority of the FBI to override customary or other international law in the course of extraterritorial law enforcement activities. Remaining criminal justice-related opinions concern the use of military drug-detecting dogs by civilian law enforcement personnel, garnishment of compensation payable by the Department of Veterans Affairs under the Child Support Enforcement Act, and the extraterritorial effect of the Posse Comitatus Act.
