I doubt the security guards who did this are constitutional legal experts who are familiar with relevant case law such as:
PAPISH V. BOARD OF CURATORS OF THE UNIVERSITY OF MISSOURI ET AL., 410 U.S. 667 (1973)
Argued: N/A
Decided: March 19, 1973
Decided by: Burger Court, 1972
Legal Principle at Issue: Whether a university that expelled a student for reprinting an offensive cartoon and a profane article headline in a campus newspaper violated the 1st Amendment.
Action: The Supreme Court reversed the Eighth Circuit decision to uphold the student’s expulsion. The Court held that ideas distastefully expressed are not unprotected, that the cartoon was not legally obscene, and that the student’s expulsion was based on content, and not on a valid time, place, and manner restriction.
Importance of Case:
The Court reaffirmed the Healy v. James (1972) application of the 1st Amendment to public universities and refused to broaden what is considered legally obscene. The Supreme Court, quoting Healy stated, “state colleges and universities are not enclaves immune from the sweep of the 1st Amendment.” In reaching this result, the Court aptly stated: “mere dissemination of ideas—no matter how offensive to good taste—on a state university campus may not be shut off in the name alone of ‘conventions of decency.’”
