AB needs to be LOCKED UP!, for a decade or better.
Just for this transgression against humanity.
Futhur incarceration to follow for other, multiple transgressions against humanity.
Manslaughter and reckless endangerment for the shooter, criminal negligence for the producer and armorer, and anyone else who handled the firearm.
Investigation into chain of custody of the firearm on the set.
Was the firearm legally possessed? Was it a straw purchase? Who purchased and supplied the live ammo?
This is just a start.
