What the heck does the DHS do, anyway?

Back here, we quietly pointed out how the U.S. Department of Homeland Security seems to be giving the Catholic Church a run for its money in terms of, well, you know. But the more you look at the organizational structure of the DHS, the more bizarre it seems.

Looking at the org chart here, everything looks fairly sane until you get here:

The Office for Civil Rights and Civil Liberties provides legal and policy advice to Department leadership on civil rights and civil liberties issues, investigates and resolves complaints, and provides leadership to Equal Employment Opportunity Programs.

Um ... huh? The DHS has an entire office devoted to civil rights? Why? This is not to belittle the idea of civil rights, but one would think there are other government departments that could provide that kind of oversight already. And that's not the weirdest part. How about this?

Immigration and Customs Enforcement (ICE), the largest investigative arm of the Department of Homeland Security, is responsible for identifying and shutting down vulnerabilities in the nation’s border, economic, transportation and infrastructure security.

At first glance, that sounds just fine until you recall that the anti-child-porn program "Operation Predator" was part of DHS under the ICE department. But why?

Again, not to minimize the problem of child pornography but in what way is it tied to the concept of federal homeland security with respect to "the nation’s border, economic, transportation and infrastructure security?" Whose idea was it to just toss all of these issues to the DHS and let them deal with them?

Given the nonsensical structure of the DHS, is it any wonder they seem to be staffed with complete cretins? Or, as we call them up here, Republicans?
