Brett Forrester was the Chairman of the prestigious Manor Hill Academy. He indirectly covered up the culture of sexual abuse of students by teachers at Manor Hill, because he didn't believe the allegations.
He continued to deny the culture of abuse, until it was revealed that his son Nathan Forrester was abused by professor and serial rapist Benjamin Strepek. Forrester then held a gathering to apologize to all of the victims for failing to acknowledge the culture of abuse. (SVU: "Lessons Learned")
