I can only hope the parents of this student are aware of this incident and decide to take appropriate action.   Abusing a mentally or physically challenged child is incomprehensible to most normal people.  The fact that the alleged perpetrator is a teacher is outrageous.  Instead of trying to "protect" the individuals involved, the DOE should be open and give basic facts; at least disclosing whether or not the parents were notified, etc.  No wonder Hawaii schools are so low on the national ranking!  This shameful incident should be investigated by either HPD or the Attorney General's Office.  Forget the DOE; they clearly don't care.
