Hundreds of people rallied outside a New York University building early Friday morning, at times clashing with police officers, to back a student group barricaded inside, The New York Times reported. The student group is demanding a variety of changes in policy, including the release of more information about the university budget and endowment, the return of a union for graduate students, limits on tuition increases, scholarships for Palestinian students and amnesty for those involved in the protest. NYU and the protesting students both accused the other side of making negotiations impossible. Those protesting are providing updates online at Take Back NYU while a parody Web site -- Fake Back NYU -- has deconstructed the various demands.
