Hindsight is always 20-20
You also have missed the point, because you also either did not read what I was replying to or didn't understand the statement. You're trying to shoot the messenger without even understanding the message.
The Swiss Cheese model is NOT some kind of blame game - it doesn't speak to who did what, or why, or were they negligent or incompetent, or didn't follow some procedure ... its simply speaks to what is. Its a tool used plot a path to disaster, and shows that multiple events are involved, and that if any one of which doesn't happen, the path if blocked that path.
Another poster earlier pointed out that in the case of Baldwin himself, there was a live round in the chamber that he did not know about. If he didn't have the gun in his hand when the shot was fired, it could have been the next person to pick up the gun who could have killed someone, or the next, or the next, or the next.
IMO (and I confess that my opinion is coloured by my experiences in the aviation industry) it is the person or persons who initially put into place the dangerous conditions, who should be ultimately responsible for what happened at the end of the chain. For example, in the crashes of Lion Air 610 and Ethiopian 312, it was the inability of the pilots to regain control of the aircraft that resulted in the crashes, killing over 300 people. Even though subsequent tests showed the aircraft were recoverable if the pilots had known exactly what to do, its was ultimately Boeing who were to blame for putting in place all the dangerous conditions in the first place.
