You gotta love Jersey girls, I guess.
I suppose this story raises First Amendment issues, but I’m not inclined to take them seriously. At most, the free speech interest conflicts with the town’s equally valid governance interests. When such irresolvable conflicts arise it is reasonable for some form of compromise rule to apply, such as the Town’s expectation to be notified prior to the event.
Assuming there’s an ordinance on the books that requires protest organizers to obtain permits, the First Amendment is irrelevant here.
