My Father is a retired English and History teacher, he also happens to be a retired Presbyterian minister. This story from Texas would disgust him. The story of Richard Mullens is a sad commentary on the situation in Texas as pertains to education. Follow the link and read it there, I don't want to quote the entire article.
I do hope that Richard Mullens gets good legal representation and sues the heck out of Bookeland's School Board. The behavior of the school board here is utterly reprehensible.
