Claremont McKenna lastest to allow protestors to shut down conservative speaker

Because if you read CMC’s policy in it’s entirety it is clear that they acknowledge the right to peaceful assembly by protestors. And then they go on to define where that right ends:

There is a major distinction between protesting a speaker and attempting to ensure that speaker doesn’t get heard on campus. When students read that policy and agree to it when they enroll, their “reasonable expectations” (which is the standard set by some federal courts in interpreting such policies) should be that they are free to protest but not shut the event down.

So I read that policy as conferring rights on both the protestors and the attendees/speaker.
