Alec Baldwin turned to social media on Monday to demand that all film and television sets that involve firearms hire police officers.

“Every film/TV set that uses guns, fake or otherwise, should have a police officer on set, hired by the production, to specifically monitor weapons safety,” the Rust actor and producer tweeted from his now-private account. On his Instagram feed, he also posted a screenshot of the tweet.

It’s his latest update following the tragic death of Halyna Hutchins, the film’s cinematographer, on the set of his film “Rust.”

Last month, while practicing a scene for the Western in New Mexico, the “Rust” actor and producer discharged a .45-caliber pistol, killing cinematographer Halyna Hutchins and injuring director Joel Souza.

Assistant director Dave Halls had handed Baldwin a weapon and assured him that it was safe to use. According to an affidavit filed to get a search warrant, Halls did not examine all of the cartridges within the revolver before labeling it a “cold gun.”

Halls told local cops that he would usually observe as armorer Hannah Gutierrez Reed spun the gun’s drum to make sure it was clear of obstacles, filled with the right ammo, and ready to use on set. Halls claimed he only saw three bullets in the chamber before handing the rifle over to Baldwin, and he couldn’t remember if Gutierrez Reed had rotated the drum at the time.

Baldwin tweeted about his “shock and sadness” following the Rust incident a day later.

“There are no words to convey my shock and sadness regarding the tragic accident that took the life of Halyna Hutchins, a wife, mother and deeply admired colleague of ours. I’m fully cooperating with the police investigation to address how this tragedy occurred and I am in touch with her husband, offering my support to him and his family. My heart is broken for her husband, their son, and all who knew and loved Halyna,” he wrote.

Baldwin earlier told reporters that he was “extremely interested” in limiting the use of firearms on set, while he acknowledged the lengthy history of movies that have utilized guns without incident and added that safety regulations should be revised.

“So what has to happen now is, we have to realize that when it does go wrong and it’s this horrible, catastrophic thing, some new measures have to take place,” he said last month. “Rubber guns, plastic guns, no live — no real armaments on set. That’s not for me to decide. It’s urgent that you understand I’m not an expert in this field, so whatever other people decide is the best way to go in terms of protecting people’s safety on film sets, I’m all in favor of and I will cooperate with that in any way that I can.”

Dwayne “The Rock” Johnson stated last week that actual firearms will no longer be utilized on his movie sets.

According to data from the Occupational Safety and Health Administration, there have been 47 fatalities in the film business since 1990, with 250 film production mishaps. Car accidents, injuries from heavy machinery, and scaffolding collapses are among the incidents.

Last week, Baldwin shared a long statement from Terese Magpale Davis, the costume designer for Rust, in which she rejected accusations of dangerous working conditions on set. In his repost of the message, Baldwin used the caption “Read this.” Davis writes, “I’m so sick of this narrative. I worked on this movie. The story being spun of us being overworked and surrounded by unsafe, chaotic conditions is bullshit.”

His remarks add to a rising chorus of industry insiders calling for a complete ban on live weaponry on set. Rachel Morrison (“Mudbound”), Reed Morano (“The Handmaid’s Tale”), Bill Pope (“The Matrix”), Edward Lachman (“Carol”), and over 200 other cinematographers said last week that they “vow to no longer work on projects” that employ operable guns for filming reasons.

The “Rust” shooting is being investigated by the Santa Fe County Sheriff’s Office, and the district attorney hasn’t ruled out pursuing charges. During a news conference last month, Sheriff Adan Mendoza stated that he believed there was “some complacency” on the set.

According to Mendoza, the bullet retrieved from Souza was a live round, and around 500 rounds of ammunition were discovered on the “Rust” set, including blanks, dummy rounds, and other suspected live rounds, and were transferred to an FBI lab for study. An attorney representing the film’s armorer, Hannah Gutierrez Reed, said in a statement last week that she inspected the bullets in the pistol shot by Baldwin before assistant director Dave Halls delivered it to the actor on set.

In a statement, Reed’s attorney Jason Bowles claimed, “No one could have anticipated or thought that someone would introduce live rounds into this set.”

Brandon Lee’s death on the set of “The Crow” in 1993 was the most recent high-profile gun-related incident on a movie production. Following that incident, Hollywood studios instituted tight safety safeguards for stunt operations involving weapons, as well as prop safety requirements. This includes prohibiting the use of live ammunition in setups in favor of blank and fake bullets.
