Would you say a three day suspension from high school is indicative of serious misbehavior?
Any suspension is indicative of bad behavior. Most people complete the entire educational process with zero detentions, suspensions or expulsions. There was always a small group of miscreants that were chronically serving detention. A smaller group experienced a suspension. A very small number were expelled. The fact of the suspension puts Trayvon in that minority of students who require more serious disciplinary action than a verbal warning from a teacher in the classrrom.
