> Black students are three times more likely to be suspended or expelled than white students

Are Black 3x more likely to break to rules or do white students get 3x more slack?

In my, somewhat limited experience it's that predominantly black schools have far more rule breaking AND slack, but it eventually leans to such egregious offenses that severe punishment results. Everyday common occurrences at black schools would be practically unheard of and result in immediate suspensions at white schools but wouldn't even be acknowledged.
