And again, the "expert" is wrong. The section of the Public Welfare Code he referenced applies to reports of abuse against a "school employee." Sandusky was not a school employee. He was an unpaid volunteer.

"
School employe—A person employed by or under contract with a school."
So the argument that they didn't call police is because Fisher didn't allege sexual acts is both legally and factually wrong.
The principal (Probst) and the guidance counselor (Smith) asked him if someone was hurting him sexually. He answered affirmatively. That's all that was required to mandate a call to CYS. The idea that Fisher had to allege some horrific sex act for them to suspect abuse is nothing more than the "expert's" fantasy. (Much like the next part of your post).
Law enforcement became involved well before a finding was indicated. CYS indicated the finding in January 2009. The police began their criminal investigation on December 12th.
The Clinton County DA's has no specific role under the CPSL if the case does not involve a school employee. That said, the transfer of the case to Centre County was done because that's where the majority of crimes occurred.
Finally, the OAG didn't violate anything in the CPSL because it was NOT conducting a CHILD PROTECTIVE SERVICES investigation because Sandusky had already been "indicated."
The OAG conducted a criminal investigation that did not involve children. The other five victims that the OAG contacted were ADULTS.
BTW, once Jerry was convicted the "indicated" report became a "founded" report.
Based on what went down here, there were two areas that weren't done correctly:
1) Clinton County should have recused itself due to its relationship with TSM.
2) A multi-disciplinary team of police, CPS, and a health care provider should have been convened to investigate.
Outside of that, the rest of what happened, including the use of a grand jury, was legally correct.
