Summary: Under forfeiture laws allowing the seizure of criminals' assets, the Department of Justice and the U.S. Customs Service take in hundreds of millions of dollars in cash and property each year. State and local law enforcement agencies, which cooperate with the federal government in these seizures, are eligible for a share of the forfeited assets. The 15 state and local law enforcement agencies GAO visited used shared assets to pay for everything from helicopters to new crime laboratory equipment to salaries. Although Justice and Customs program guidance requires state and local agencies to use shared assets strictly for law enforcement purposes, acceptable uses under the guidance can be broadly interpreted, leading to, in GAO's opinion, questionable expenditures. Justice, aware that existing guidance on the use of shared assets is vague and confusing, is considering revising and clarifying the guidance. GAO notes, however, that such changes need to be planned and undertaken jointly by the two agencies.
