I get that.  But I have to wonder...do you not trust the school to place the safety of their students first?  Do you not trust the administration to look out for the kids' safety?  That's completely apart from the privacy of the suspended child and his family, which I'm sure you agree are extremely important.  If you do not trust the school to make decisions with the welfare and success of all its students in mind, maybe it's not the right place for your student.  

As for the "8 missed classes" policy, it sounds like that's based on absenteeism rather than a suspension.  But I think if my child had emotional or academic struggles, I'd be overjoyed to have his case looked at independently of policy.  All situations are different, and no one size fits all.  I imagine if your child were going through something similar, God forbid, the school would certainly look at ways to keep him or her on track while keeping everyone safe.
