Parents who's children under 18 commiting acts of violence should be tried in court for negligence or child abuse.

Bad parenting should be as punishable a law as any crime on society. If you have a child and they end up contributing to violence and hardships for other people then you as a parent should be held liable for the acts of violence that they make against any other. If a child commits acts of violence ending in the death of another human being the parents of this child should be tried as well for negligence of a minor and punishable to the same sentance as their child.
