If you want a peek at what's going on at the other end of the educational spectrum, there's a film at academicbias.com you may want to watch. It runs about forty-five minutes, is free, and can be watched on RealPlayer, QuickTime, or WindowsMedia. No short film can give more than the smallest taste of this large a subject, but if you haven't heard much about the curtailing of freedoms on college campuses in the US, it might be worth your time to watch it. Or listen while you do something else.
Sadly, nothing in the film surprised me. I have read about many similar cases over the past 5-10 years.
