Black teacher, black kids = No problem
White teacher, black kids = Fired
Sad...but true!
When I was in High School, I witnessed my Vice Principal break up a fight between two students. He was 5,1,about 50 and white and the two kids were over six foot and black.
He got in between them, pushed one against the wall and jammed the other one into a door way until help arrived.
He then grabbed them both and dragged them to the office. \
Of course that was back in the late 70s...
