universities are beginning to do what Fr. Ted did back in the 60's....i.e. make it quite clear that if demonstrators impede the function of the university, they'll be dealt with...
"...anyone or any group that substitutes force for rational persuasion, be it violent or non-violent, will be given 15 minutes of meditation to cease and desist."...and those who did not would face immediate suspension, expulsion and/or removal.
This is a matter for the universities' leadership.
