I recently traveled to Southern Methodist University (SMU) donning a human sandwichboard to recruit pro-lifers and start a pro-life group. I had an open invitation from a couple SMU students to come to campus to start conservative groups at SMU.
SMU was definitely a tough campus to find pro-lifers and those willing to get involved. Several passerby openly stated to me that they were not explicitly not pro-life.
About an hour into my recruiting, the campus police came up in two SUVs and asked me to leave. A leftist on campus probably reported me to the campus police for "trespassing."
Unfortunately, I couldn't get a hold of the students who invited me to campus who could vouch on my behalf. I don't blame the police for asking me to leave if I couldn't produce the students who invited me.
According to the police, even if I could have done so, those students would've had to get permission from the university administration to exercise their free speech with a human sandwichboard, and could only do so within "free speech zones" on campus.
The police officer said, "It's just to make sure that all the proper resources are covered."
According to the Foundation for Individual Rights in Education (FIRE), SMU, though a private university, is still required to protect the free speech of its students:
All students of the University are citizens of the community and members of the University, and as such are guaranteed freedom of expression, inquiry, and assembly. (Student Handbook: Code of Conduct- Student Rights, Freedoms & Responsibilities 10-11)
SMU could be courting legal pressure if it doesn't act according to how it presents itself publicly to students.
