That’s true, but to my point about judging systems not only by how they work (or don’t) when adhered to, but how they they work (or don’t) when they are not, as here, strictly adhered to, it is equally true that, had industry safety protocols precluded the use of real firearms capable of firing real bullets, there’s every likelihood that even with live rounds on set and a host of other failure, this would not have culminated in the death of a wife, mother, and cinematographer.
