A pro-life student group gets permission from the university to write messages in chalk on a campus sidewalk. After they’ve done so, along comes a bossy, officious prof who tells them they can only exercise free speech in the school’s free-speech zone — but the speech-zone policy no longer exists. He goes to his morning class and comes back with a number of students who want to confront the pro-life group. They all begin to erase the chalked messages. Will this brazen assault on free speech just be forgotten?

Apparently not. I write about the case in my latest Forbes article.
