And I personally have mixed feeling on that charge. I think as an actor who pulled the trigger, he is not responsible for reasons I've already stated. I'm fine with him being charged as a producer who cut corners and ignored safety concerns, but that doesn't seem to be what is actually happening here, because there are other producers who are more responsible and were not charged. 

For what it's worth, Halyna was a friend of mine. I can't begin to tell you how much this all pisses me off. I think Alec Baldwin is a scum bag. I just don't believe it's an actors responsibility to make sure a prop gun is safe to handle in set.

There are a couple of mitigating factors in play here, I believe. I'm under the weather today and don't have the energy to research what I've heard (I'll try to do so later), but it's been said that the armorer wasn't on the set during the shooting. All firearms are to be securely locked away if the armorer is not present...so how did Alec get the gun? Did the armorer leave it laying around, or did Alec instruct someone other than the armorer to remove it from the safe? If it's the latter, he would be culpable.

It's also been rumored that Alec was not supposed to aim the firearm at the camera person at all during the scene that was being filmed. It's possible that he wasn't even supposed to remove the gun from its holster. It's been said that Alec removed the gun, aimed it at Halyna (thinking it was not loaded) and pulled the trigger to display his irritation at either the director or cameraperson. If this is the case, he could be considered culpable as this was reckless behavior.
