Turns out, the DHS did not visit that UMass/Dartmouth student. Federal agents' visit was a hoax: Student admits he lied about Mao book.
Whatever this student's motivation (embarassing the Bush administration, garnering attention, pathological lying, whatever), it's certainly become a topic in the library and the anti-Bush communities. I'm not saying it would have been nice for this to be true, but it does have that "boy crying wolf" quality to it. Should such a thing really happen, it'll be just a little bit more difficult for anyone to believe. Anyone, that is, who isn't part of the "Automatically Bash Bush" brigade.
