The officers are following their orders. But why would a chancellor of a PUBLIC institution have the power to tell people they can't PUBLICLY demonstrate their first amendment rights unless they are violently demonstrating?
Civil disobedience is a constitutional right. Disobedience does not equal violence.
You say, "all I can gather is that you don't respect the laws," but violating one's right to civil disobedience is disrespectful of laws.
