That’s a matter for redress in the civil courts, via litigation. It’s not a green light to break the law.
Just because cops do not stop every speeder does not mean you can speed.
Sorry, it’s the law.
The law is,
if some off campus special interest groups get to propagandize, speak, distribute literature . . . then it must be a level playing field for all nonviolent groups to do the same.
That’s THE CONSTITUTION.
Do you have a problem with that?
