DHS Backpedals on "Rightwing Extremists"

I'm sure that nobody at the Department of Homeland Security could have foreseen the firestorm of protests that a short report on possible threats of domestic terrorism by rightwing extremists has stirred up.

The report implied that military veterans returning from Iraq and Afghanistan might stage attacks in this country: "The possible passage of new restrictions on firearms and the return of military veterans facing significant challenges reintegrating into their communities could lead to the potential emergence of terrorist groups or lone wolf extremists capable of carrying out violent attacks"

Today, Homeland Security Secretary Janet Napolitano apologized for offending veterans.

It's good that she did that, and the report has been removed from the DHS website, but my question is this: What action has been taken against the person or department that created the report in the first place? Has anyone taken them behind the woodshed for a little discussion about how our veterans have served their country with honor and distinction, and how they are probably the last people who would ever give up their beliefs and love of country to stage any sort of attack?

What exactly is this mindset at DHS, and how pervasive is it?
