Would present laws apply to campus demonstrations?

For all of the demonstrations that were taking place on campuses across North America, would the present laws not apply?

The full range of criminal laws apply to activities on campuses. A university administration need not authorize the police to enforce criminal law measures (other than trespass laws) when crimes are being committed (like the mall scenario demonstrated). To be clear, the criminal law is not always the answer (or the only answer) for many activities that should be addressed through, for example, disciplinary proceedings or other non-criminal proceedings against those who create a poisoned environment for students on campuses.
