You will never understand Xena....the issue is security against intruders plying the area; you do not have the whole picture so you will never understand. Burglars and intruders silently entered the building and worst the occupants are exposed to danger...it happened already during daytime and nightime. The reason why these intruders were able to sneak in was due to an opened door left unlocked. What the hell are some doing outside is not much of a concern, but they also should watch their acts because they carry the name of the school wherever they are...aren't setting a good moral behavior in the first place must be observed by a teacher? If their acts would put the other occupants in danger is that not also a criminal act?

You will never understand because you do not know the real picture. If they are responsible adults they will not be sneaking late at night keeping the doors open and giving an opportunity to intruders.
