Hello. The answer to your first question regarding a requirement to report a certain incident depends on the full facts of the situation. The statement of the incident and the questions raised are ambiguous as written.  You talk about not being 'sure what my legal recourse is'.  I suggest you should confer privately with an attorney to whom you confide the facts of what occurred and your worries and concerns.  Certainly inform the attorney of any wishes you have regarding choice of action.  All the best.
