If the only legal way to protest is to do it alone in a field then the legality of the protest is a moot point. Protesting is about the public getting heard and the cost is to productivity. The cost shouldn’t be an arrest record and stigma. This isn’t because two or three assholes are disrupting a campus. Students are getting arrested in dozens. Professors are getting arrested too. What the colleges and universities are doing against their own students is unacceptable.
