Which part: the people that think an actor with minimal firearm safety/knowledge is supposed to double check the work of the armorer (the expert)

Or

The people that think anyone that touches a gun, even a prop gun, should be an expert?

I agree with you, the actor **has** to trust the armorer which is supposed to be the expert.

That being said, I don't know exactly how things went down. If Alec is one of the producers responsible for getting a clearly unqualified armorer a job, then some of the blame is on him.
