For confirmation that the vandal (Roderick King) was a Student Senator, see here. The vandal's rationale:
In 1973 it was made a Constitutional right for a woman to have an abortion. It's not your responsibility. Since it's a right, you don't have the right to challenge it.... Do not put this [display] in front of all of us ... it is not your right.
I'd like to hear what actions the university or the student senate will take against Senator King for his vandalism.
Note, incidentally, that the use of the university's property for the exhibit had indeed been authorized by the university. (Even if the parklike area on university property was a traditional public forum in which speech had to be allowed, or a designated public forum that the university opened up for speech, it's likely that the university could bar installations planted in the ground — but it appears that the university did not impose any such content-neutral limitation.) Here's UWSP's response, which strikes me as very good:
The University of Wisconsin-Stevens Point has received several communications regarding the May 1, 2008, display by the student organization, Pointers for Life, and the disruption of that display by opposing students.
The university values free expression and the open exchange of ideas. Pointers for Life is a recognized student organization that followed university procedure in staging its event.
The student who disrupted the display not only exhibited inappropriate behavior, but demonstrated intolerance that is unacceptable on the UWSP campus.
University procedures are being followed. In accordance with the Family Educational Rights and Privacy Act, which protects our students from disclosure of their educational records, results of those procedures will not be made public.
