What factors may come into play in his criminal culpability.
Did he know that guns were being used for plinking?
Did he know that ammo had been seen laying around?
Does he know what the industry standards are for safe gun handling?
If the answer to any of the above is yes, then it would seem that he'd own some responsibility beyond civil. If he was aware of 2 or more, I think a very solid case could be made.

Treat all prop guns as if they are real.
Treat all guns as if they are loaded.
Unless you are actually performing or rehearsing, the property master must secure all firearms.
The property master or armorer should carefully train you in the safe use of any firearm you must handle. Be honest if you have no knowledge about guns. Do not overstate your qualifications.
Follow all instructions given by the qualified instructor.
Never engage in horseplay with any firearms or other weapons. Do not let others handle the gun issued to you for any reason.
All loading of firearms must be done by the property master, armorer, or experienced persons working under their direct supervision.
Never point a firearm at anyone including yourself. Always cheat the shot by aiming to the right or left of the target character. If asked to point and shoot directly at a living target, consult with the property master or armorer for the prescribed safety procedures.
If you are the intended target of a gunshot, make sure that the person firing in your direction has followed all these safety procedures.
If you are required to wear exploding blood squibs, make sure there is a bulletproof vest or other solid protection between you and the blast packet
Use protective shields for all offstage cast within close proximity to any shots fired.
Appropriate ear protection should be offered to the cast members and crew.
Check the firearm every time you take possession of it. Before each use, make sure the gun has previously been test-fired offstage. and then ask to test-fire it yourself. Watch the prop master check the cylinders and barrel to be sure no foreign object or dummy bullet has become lodged inside.
Blanks can be dangerous. Even though they do not fire bullets out of the gun barrel, they still have a powerful blast that can maim or kill.
Never attempt to adjust, modify, or repair a firearm yourself. If a weapon jams or malfunctions, corrections shall be made only by a qualified person. Notify a prop person or Armorer immediately.
When a scene is completed, the property master shall unload and take possession of the firearms. All weapons must be cleaned, checked, and inventoried by the prop department after each performance.
Live ammunition may not be brought into the theater or onto a studio lot.
If you are in a production where gunshots are to be fired and there is no qualified property master, go to the nearest phone and call Actors’ Equity Association. A union representative will make sure proper procedures are followed.
State and federal safety laws must be honored at all times.
If any of the above safety tips conflict with the instructions given by a qualified instructor, abide by the instructions from the qualified instructor. If you are still not sure, contact your Equity Business Representative.
