Even if Baldwin wasn’t the one holding the gun, even if was in the hands of a completely different actor, he should have been charged as part of the Producers for failing to provide a safe work environment.
Then you’re advocating for a fundamental change to way America manages workplace safety. If Baldwin hadnt been the one to pull the trigger he would never have been charged in a million years. Criminal charges require some level of intent , including involuntary manslaughter or negligent homocide. Unless you can find communications that show that the producers knew the workplace was unsafe and purposely didn’t take action (not acting sufficiently probably wouldn’t be enough), no charges were even possible.
At most the family of the deceased would have had a strong civil cause of action against the production company, because that’s how workplace safety is handled in 99 percent of cases in the US. That civil liability can then be quantified, analyzed, and insured against. I’m not saying this is a good thing , but criminal charges for company owners have never been how these things have been handled.
