Intelligence and Law Enforcement: Countering Transnational Threats to the U.S. [Updated December 3, 2001] [open pdf - 263KB]
This report looks at the separate roles and missions and distinct identities of intelligence and law enforcement agencies. Coordinating their efforts has raised significant legal and administrative difficulties that have been only partially overcome despite the creation of elaborate coordinative mechanisms under the oversight of the National Security Council. Some observers also have expressed concerns about the greater use of information derived from intelligence sources in judicial proceedings, fearing that it may lead to over-reliance on surreptitious means of information collection and, thus, undermine civil liberties. Other observers have cautioned that redirecting intelligence assets to collect information for legal cases may reduce support available to military commanders and policymakers. Some others believe that there may also be an overemphasis on law enforcement in dealing with problems rising abroad. The report notes the employment of covert actions by intelligence agencies in certain law enforcement efforts.
