Let's see if I understand everything. The *facts* of the case are not released yet; however this teacher assumed that Treyvon, by virtue of his race - was ruthlessly hunted down and murdered for fun. Now, she uses her position as a 'teacher' to 'educate' the kids about circumstances that exist only in her head.
And she wonders why she's been fired? Granted, the Administrators are prohibited from saying the actual reasons for her dismissal, lest they be sued for privacy issues. But, IMHO this certainly seems to be justifiable pattern to remove a "teacher" from a classroom.
You can take it to the bank she was fired for other reasons. She’s the once claiming it has to do with that as a ploy to get her job back.
