College Republicans at San Francisco State University held an anti-terrorism rally last October during which they stepped on pieces of paper painted to resemble the flags of the terror groups Hamas and Hezbollah.

Another student filed a formal complaint accusing the Republican group of attempting to incite violence and creating a hostile environment. The school took it seriously enough to schedule a formal hearing.

The students’ rights group called the Foundation for Individual Rights in Education said the hearing was illegal—contending a public institution cannot prosecute students for political protests.

The hearing was held—and the College Republicans were exonerated. University President Robert Corrigan says the students did nothing wrong and the charges were groundless.
