On Nov. 30, 2021, a 15-year-old boy killed four students and injured seven others in a shooting spree at Oxford High School in Michigan. Just three days after the shooting, Oakland County prosecutor Karen McDonald made the historic decision to charge the shooter's parents, Jennifer and James Crumbley, with involuntary manslaughter. "I know we have a legal duty as parents to protect other people from dangerous kids," McDonald says in the documentary.
