I think there is must be something in that schools rules and regulations that will allow them to do that. But the school should told the student that they would have contacted the students parent(s) and also the police department, and done it also. I have not heard of the story, so I don't know all the facts.
But now the student can say that they (staff members) touched her in an inappropriate manner, and now the school and the staff members would be on the hot seat.
Starscream- you said it was on CNN? I will have to look that up.
