Then you have your immigration agencies: United States Customs & Border Protection, Citizenship & Immigration Services (CIS), and United States Immigration & Customs Enforcement (ICE). These agencies were preceded by the Immigration & Naturalization Service (INS), Border Patrol, and United States Custom Service. It might be best to bring back INS and eliminate CIS & ICE. In addition, both INS and Customs & Border Protection should be transferred to the Justice Department (note: both INS and the Border Patrol were formally located in the Justice Department before Homeland Security was created).
Finally, all the other agencies in Homeland Security can be transferred to the Justice Department.
So there you have it, Homeland Security is eliminated from the federal budget, and its agencies are either transferred, privatized, or eliminated.
