I read the newpaper review on The Age. I hope that both drivers that hurt the little girl were punished severly. I have a little boy and God help anyone who hurts him purposely or accidentaly. What are the punishments and procedures for dealing with negligent vehicle accidents that result in injury or death to innocent bystanders? I hope articles like that one help to deter drunk drivers and idiot drivers because it only takes one mistake for one second to drasically change someone's life.
