Politically Incorrect Politically Correct Speech

Mark Steyn catches Homeland Security Secretary Janet Napolitano using an incredible euphemism for terrorism. She says:

In my speech, although I did not use the word "terrorism," I referred to "man-caused" disasters. That is perhaps only a nuance, but it demonstrates that we want to move away from the politics of fear toward a policy of being prepared for all risks that can occur.

But shouldn't that be "person-caused disasters"?
