Walker, I get what you are saying about the therapist being in a "conflict of interest" position.
I have also wondered about JH volunteering for an experimental drug.
Thinking it through tells me this.
Fenton did not notice anything about JH until sometime in the" first 10 days of June". JH quit school on the 12th of June, or thereabout. So, there was no time to refer him to anyone else. He was gone from there. If they tried to call him just to help or suggest, he may not have answered, or cared.
Test drugs I don't think the school would do if they are paying his way to the tune of $26,000 per year. Allow students to take notes during such a thing perhaps, but not participate given outcomes are unknown and liability for the student, waiver or not.
JH taking drugs of any sort, homemade, street made, lab made, that is obvious. That was his personal choice though, and not related to the school.
