The crew members acknowledged that theRustproduction had “areas that were more challenging” and imperfect, though they maintained it was a “professional” set with “areas of brilliance.”

“The descriptions ofRustas a chaotic, dangerous, and exploitative workplace are false and distract from what matters the most: the memory of Halyna Hutchins, and the need to find modern alternatives to outdated industry firearm and safety practices,” reads the letter.

Days after the tragedy, a crew member who worked on the film told PEOPLE thatthere were “red flags” on set leading upto the incident and that the filming environment felt unsafe at times. Reports also mentioned people on setstaged a walkoutafter some members of the camera crew wrote resignation letters the night before the incident.

In the new letter, these crew members said, “While it is true that a few crew members quit prior to the accident, the vast majority of us remained, never feeling the need to protest or quit. We were enjoying our workplace. Those disgruntled few do not represent the views of all of us.”

The letter claims that “working morale on set was high,” and that “from the director down to the production assistants, all departments worked well together, collaborating and helping each other achieve shared artistic goals.”

The crew member who previously spoke to PEOPLE said they personally felt it was “set etiquette” to “stay in your lane” and “not to say anything.”

“… We are supporting each other and cooperating with investigators,” the crew members said at the end of the open letter. “We kindly request that your speculation and generalizations about us and our colleagues be sympathetic until all investigation is concluded. We are grateful to our many friends and family that have reached out to us privately to offer compassion and support.”

The letter comes one week after Baldwin’s emotional ABC News interview aired in which the actor told George Stephanopoulos that he has been “struggling physically” in the wake of the shooting but that hedoesn’t feel guilt for what happened.

“Someone is responsible for what happened, and I can’t say who that is, but I know it’s not me,” he said, adding, “I mean, honest to God, if I felt that I was responsible, I might have killed myself if I thought I was responsible. I don’t say that lightly.”

“I would go to any lengths to undo what happened,” Baldwin said at the start of the interview.

“I want to make sure that I don’t come across like I’m the victim because we have two victims here. All of what happened that day leading up to this event was precipitated on one idea, and that idea is that Halyna and I had something profound in common,” he added, “that is we both assumed the gun was empty, other than those dummy rounds.”
