This HS principal was interviewed and it was shown on CNN. I don't know where. Earlier in the week parents complained about teachers talking about Ferguson so he had teachers stop it. Now parents are complaining that he stopped it. Argh. Now he is going for something in between, talking about it but as part of a big picture.
In HS back in the early 1980s parents were told if they didn't like what the teachers taught they are free to remove their child from the school. It was though a private Catholic HS. This school is public so different rules I assume.
