Dunno if I can agree here mate - why should one suffer coz of the rest!!?
Or worse - if a group of 2/3 don't own up - why should the rest suffer too!!?
I'm not your mate.
Also, because (a) if the teacher can't prove who it is, a class detention will often bring out the culprit, and (b) it is pretty rare - from my experience, at least - for a class detention to be given without a significant majority in the class being ********s.
