You are correct, you can't justify an attack on a child. But you can't justify the lack of parenting when the child doesn't have respect animals enough not to taunt them. You think that kid laying in bed is going to admit to taunting the animal? He's a scared little boy, which is much different from the way he was acting when he taunted the dog. It's true, eye for an eye isn't the best idea... but this kid got what was coming. Live and learn. And don't sue because of your own ignorance.
