Prison conduct and contraband: Four things we learned from Erik Menendez's parole hearing

Erik and Lyle Menendez, who have spent decades in prison for killing their parents in 1989, were denied parole after separate hearings in California this week. Both brothers' parole denials were primarily based on their behavior in prison, including rule violations such as unauthorized mobile phone use, rather than the original crimes. Despite claiming self-defense based on alleged abuse by their father, the parole commissioners cited concerns about anti-social personality traits and institutional misconduct that suggested they might break rules in society.
