Title 50 › Chapter CHAPTER 44— - NATIONAL SECURITY › Subchapter SUBCHAPTER I— - COORDINATION FOR NATIONAL SECURITY › § 3039
Intelligence agencies may collect information outside the United States about people who are not U.S. persons when a U.S. law enforcement agency asks for it. They may do this even if the law enforcement agency plans to use the information in a criminal or counterintelligence investigation. If the Defense Department helps, only four agencies may do this: the National Security Agency, the National Reconnaissance Office, the National Geospatial-Intelligence Agency, and the Defense Intelligence Agency. Military members cannot take part in arrests. Help cannot hurt U.S. military readiness. The Secretary of Defense must make rules for how the Defense Department acts, including protecting sources and methods. A "United States law enforcement agency" is a federal agency the Attorney General names. A "United States person" means a U.S. citizen, a known permanent resident, an unincorporated group mostly made up of U.S. citizens or residents, or a U.S.-incorporated company unless it is controlled by a foreign government.
