And before you try taking this off into yet another irrelvent tangent, my best recollection of DHS had all other agencies reporting to them. A
quick google search, seems to reinforce that, "for the most part"
The Department of Homeland Security officially took form on January 24, 2003, with Tom Ridge serving as the first secretary of the department. However, the department only had a skeletal structure until March 1, 2003, when the majority of agencies that would constitute the bulk of the new department were formally transferred into it. On March 1, 2003,
the following federal agencies were transferred to the department:
the Coast Guard;
the Secret Service;
the Customs Service;
the Federal Emergency Management Agency;
the Transportation Security Agency;
the Commerce Department's Critical Infrastructure Assurance Office,
the Defense Department's National Communication System;
the
FBI's National Infrastructure Protection Center,
and the functions of the former Immigration and Naturalization Service.
The act also aims to facilitate homeland security information sharing procedures in an effort to maximize intelligence data analysis and utilization capabilities.
