Fighter arrested after video shows assault on 13-year-old stepson in Brazil

In Belo Horizonte, a fighter was taken into custody after video evidence documented his assault on his 13-year-old stepson, leaving the boy with a broken jaw. The footage removed the uncertainty that so often shields domestic violence from accountability, allowing the courts to act with unusual swiftness and clarity. A preventive detention order now holds the man while the case proceeds — a reminder that the protection of children sometimes depends on the rare fortune of an unblinking witness.
