According to reports, the students had posted pictures of themselves on Facebook which the school subsequently deemed as lewd, obscene or immoral. The students were subsequently prevented by security guards from entering the campus to attend the commencement exercises.
If I understand things correctly from news reports, the students were allowed to graduate but just not allowed to attend the commencement exercises. If this was the case, then the school’s decision was, in fact, a win-win situation for the school and the students. Perhaps, then, the better option for the students – and their parents – would have been to cut down on their losses, accept the school’s decision and move on from there.
