No phone in the hallway?

The newly enforced rule is unfair and unnecessary. We are college students and should be treated as such.They expect us to act like proper college students when we don't even have the same rules as them. What if plans have changed with someone's ride and they didn't know? They couldn't look at their phones in the hallway without a teacher taking it from them. This is all because some students downloaded a projector remote on their cell phones that most of the students did not know about. The  good students of this high school should not be punished for what a small percentage of the unruly students have done. If a murder was caught the whole town wouldn't be punished, why should all of the freshmen and sophomores be punished? Why should the majority get punished to get to the few?
