Probably.
Someone hands you a weapon, the assumption should always be that it is loaded.
Life is not a movie.
“In the US military, if you negligently fire a round and kill someone, you will be charged with murder. If you negligently fire a round causing no injury at all, and you are in a special operations unit, there is a good chance you will be kicked out of the unit. Would you trust a pilot who forgets to drop landing gear?”
From the article. And true. But also true for non-military. There was gross negligence here. That’s not a simple accident.
Furthermore, they were having issues with unions. I put nothing past them. Issues like that should have raised the importance of following all safety protocols. Check, double check, maybe even cancel. All live rounds should have been removed from the set. There should have been a zero tolerance for them. Remember, Baldwin wasn't just an actor, he was a producer. These responsibilites fall to him.
The first rule of Firearm Safety might be “Treat every gun as if it were loaded” but the first rule of Firearm Handling is “Never pick up a gun without confirming whether it is loaded.”
So that’s strike two.
