Mr Babb chose to discharge his firearm inside his home,  putting himself, his roommates and his  surrounding neighbors' lives in danger. Every day innocent children / people are killed by bullets piercing walls and landing in brains and aortas from someone else's gun. 

He also made the choice to stand in his front doorway and point a weapon with a scope at an officer. That officer is going to shoot before getting shot.

Pretty sure if your toddler was killed by Mr. Babb's stray bullets, you'd be singing a much different tune.

His choices. It's all on him.
