This is scary, nuts, and not a good glimpse of our future coworkers.
As a former teacher, specialist in the research in effective teaching and school effectiveness, and administrator, I would say that something is terribly wrong here. First, any principal who would allow such things to happen in his or school should be fired. Second, I would lay odds that the teacher is truly lacking in classroom and disciplinary management skills, and/or in ability to connect with her students . Those three things are almost always the sources of such chaos.
Saw that on the news..shouldn't the problem child be removed, not the other way around?
Seems common sense is a rare commodity.
