The HSA also established the secretary of homeland security as a cabinet-level position. The HSA imposed the largest federal government reorganization since the Department of Defense was created via the National Security Act of 1947 (as amended in 1949). It also includes many of the organizations under which the powers of the USA PATRIOT Act are exercised.

Background

The new department assumed a large number of services, offices and other organizations previously conducted in other departments, such as the Customs Service, Coast Guard, and U.S. Secret Service. It superseded, but did not replace, the Office of Homeland Security, which retained an advisory role. The Homeland Security Appropriations Act of 2004 provided the new department its first funding. A major reason for the implementation of HSA is to ensure that the border function remains strong within the new Department.

The act is similar to the Intelligence Reform and Terrorism Prevention Act (IRTPA) in reorganizing and centralizing Federal security functions to meet post–Cold War threats and challenges. Like IRTPA, there are some inherent contradictions in the bill not solved by reorganization. These reflect compromises with other committees needed to secure passage, but the result is at times inconsistent or conflicting authorities. For example, the act identifies the Department of Homeland Security's (DHS) first responsibility as preventing terrorist attacks in the United States; but, the law's language makes clear that investigation and prosecution of terrorism remains with the Federal Bureau of Investigation and assigns DHS only an analytical and advisory role in intelligence activities. Similarly, with Critical Infrastructure Protection (CIP), which relates to the preparedness and response to serious incidents, the act gave DHS broad responsibility to minimize damage but only limited authority to share information and to coordinate the development of private sector best practices.
