STOP ENABLING THE INDISCIPLINE.
In any school, a few troublemakers give the vice principal most of the work. Treat the incidence of suspensions as something subject to "disparate impact" analysis, expect troublemakers to take advantage of the rules. "Reduce suspensions for minority students in order to make your numbers look good." That won't turn out so well for students deprived, accordingly, of functional classrooms. Thanks, Obama.
