First off there was no designated armorer (HGR’s contract expired.)
Secondly, according to that process, the armorer is supposed to be checking it in front of him, handing it directly to him, and watching him and the firearm to ensure safety.
That did not happen. We know that didn’t happen because if it did, nobody would be dead.
Further, as the person holding the weapon, it’s his final responsibility to handle it safely. If an expert tells him “this is safe,” and it’s obviously not safe… then it’s on him.
Pointing weapons at people and pulling the trigger; without at least checking its loading is unsafe, and Baldwin did not do that. He didn’t even see someone else that.
When the consequence of not being anal about something is death, you’re expected to be anal. The consequences of not following gun safety is death. And this is why.
