One teacher, having heard of his reputation as a troublemaker, singled him out at the start of the school year—literally, singled him out. She made him spend the semester behind a partition in the back of the room, separated from the rest of the students. Over time, that led to his rejection of the teacher, of his schoolwork, of school. That led to the streets, to drugs, to violence. Jon connected the dots by concluding, “Stick me behind a partition, and I grow up and kill someone.”
