It is an excellent comment, yet I’m not so sure he would have checked the gun, even if the scene required he point it at himself. AB apparently trusted the chain of custody of the gun. And that’s where I see the problem. As an experienced actor, arguably the biggest name in this now defunct movie - but more importantly, one of the main producers - he should have been aware the production was in shambles. Had he walked off the set the first time safety protocols were breached, the movie set would have shut down until corrections were made. The armourer should have been fired.
Halyna’s life, along with the lives of everyone on the set, was in peril days or weeks before her fatal shooting. Yet those in charge allowed the cameras to keep rolling. Reckless and unconscionable. Halyna’s family and friends, along with everyone that witnessed the shooting, and AB himself, will have to live with that horror for the rest of their lives.
