Our saftey and welfare of our class and our education. He has major anger issues and takes it out on us and our education. Also, he told us to bring a gun to school and shoot him. This is extremely unprofessional in an educational enviroment.When he has his public displays of anger, he rushes through our lecture and does not explain what he is doing. He has thrown chalk in the classroom in result of an issue in class. Several of us have complaned to the assistant dean and Dr. Ball. As you can all see, there has been no repercussion of this.
