... seems it'd be a hard case to prove to 12 regular Joes. I could really care less (about him... his case... whatever), but proving enough negligence might not be easy. Thought we'd see civil suit, but not really criminal.

He is not only the shooter he’s ultimately responsible for safety on set. 

He was loading real ammo into prop guns and shooting them for fun in the off time 

Then because no one checked he shot one of those real bullets at someone intentionally.

It’s a fairly simple manslaughter case. Like even if he wasn’t the actual shooter he would be facing these charges (like the armorer)
