That makes it sound like Baldwin was a victim of others' negligence. But he's not just an actor but the producer, so the buck for repeated safety violations stops with him.
Dummy rounds are generally visually similar to live rounds (not blanks, which apparently are referred to as “live rounds” in film), so a readily distinguishable from blanks.
Most actors receive training with firearms so they can handle and fire them convincingly on set. Baldwin has made a several films where he handled firearms, so I'm certain he's had safety training at points in his career. Taking someone's word for it being a "cold gun" is irresponsible.
"Alec Baldwin is producing and starring in the independent Western action movie “Rust” with Joel Souza directing from his own script, based on a story by Souza and Baldwin."
...
"Highland Film Group will launch international sales at the upcoming Marché du Film Online, which launches on June 22. CAA Media Finance is handling the domestic rights, and BondIt Media Capital is financing. "Baldwin is producing through his El Dorado Pictures banner alongside Anjul Nigam and executive producer Matthew Helderman. Baldwin and Nigam produced Souza’s “Crown Vic.” Anna Granucci is also producing with Elizabeth L. Barbatelli as an executive producer."

So the speculation that "it sounds like he may have just been an actor who was given a producing credit as partial payment for taking a lower salary" that I commented on is clearly not correct.
As to the "decisions", I'm sure he didn't sit down and sweat the operational details ("decisions"), where to get film, etc. But for decisions such as "who'll be the DP?", "we'll shoot in Santa Fe because it allows for non-union crew", or minimally chiming in on the production crisis and crew accommodations issue, are you seriously claiming Alec Baldwin was just hanging out chit chatting with the crew and was not involved at all? He's not some airhead pretty face, he's a business man as well and he is making a film with partners.
Rust has (currently) 5 credited executive producers, 6 producers, and a co-producer.
Even if Baldwin’s producer credit reflects an actual responsible role and not a producer credit in lieu of additional pay, no one not involved in the production can say from the credits alone that Baldwin had any responsibility over the actions that led to the incident, beyond that which he had as an actor (which is not none, to be clear.)
