This is a long time in coming, but I have finally updated my original posting, Andover School Committee Meeting Report: Viewpoint Discrimination Edition, with video of the Superintendent of Schools apologizing for the appearance of Wheels of Justice at Andover High School, as well as a transcript of the remarks and the notes from one of the angry parents who addressed the committee. Scroll down to where the videos start.
This should prove a valuable resource for any school facing a visit from these people in the future.
