Target is facing a lawsuit filed by a mother who says her son committed suicide after he was forced to take part in a humiliating disciplinary event in front of co-workers and customers. The suit claims 22-year-old Graham A. Gentles, a former cashier at the retail chain’s Pasadena store, was humiliated when he was subjected to what the family’s attorney called a "walk of shame," a ritual during which the employee is paraded around the store in handcuffs."I don’t want any other mother to have to go through what I’ve gone through," said Graham’s mother Virginia Gentles, who filed the lawsuit. "This is my only child."
