You’re passionate about an issue and you want to take a stance. So, you gather up a bunch of students and organize a protest—a sit-in, a walk-out, a picket line, etc. But does the school have the power to shut it down? Aren’t these protests protected by the First Amendment? 

No, school administrators do not have the right to search a student’s phone if a student is caught using their phone during class, even if that student protests its taking.
