I'm not defending Baldwin, but all actors are to study the script, be on time, don't show up hung over, know their lines, etc... I highly doubt there's 1 actor male/female that's ever checked the gun prior to filming, and that's 1000's of rounds shot through the years by many many actors.
It's someone's job to be in charge of the firearms, the animals, and even the food cart...but none of those are the actors job or responsibility. I don't like the guy, but do feel kind of bad for him considering the damage he's done to some people's lives...and have to live with the fact that he took a life, and wounded another.
It is ultimately the responsibility of the clown holding the firearm...and if they are not competent then they do not get to hold firearms.
That is how it works for the rest of us commoners.
