JMHO, but based on this, I think there's probably a lot more to the story than has been reported here.
I agree, we're not getting the whole story. I was tipped by another part of the article which stated,
"School boards hold such hearings in a closed session, but parents have the right under state law to request that such sessions be open. Herpin didn't make that request but did speak to reporters after the hearing."
IOW, she wants to get her side of the story out in the court of public opinion, but not the school board's side of the story.
And it's working. Just look at some of the stupid posts on this thread.
