I think the take away on this is:

As is, currently, actors are not responsible for checking their prop weapons on set. No actor is ever expected to do it, because there are people responsible for it. In the event of an incident, in the current standard practices, no one can reasonably blame the actor.

But, systematically, it shouldn't be that way.

We can't look at one incident and say "clearly the actor was in the wrong" because culturally, it's X Y and Z tech's job to check the firearm. But cultures within an industry can shift. Currently, firearm safety on set isn't everyone's job. But it should be everyone's job. The system should be better, because firearm safety is a demonstrably life-or-death process.

How do you change the system? By holding productions liable when stuff like this happens. You sue the absolute shit out of the producers, so the producers have a crippling fear of NOT improving the system.

You don't hold the actor Alec Baldwin responsible. You hold the producer Alec Baldwin responsible.

Does it count as food poisoning if it's not technically food?

I posted a similar question a couple days back, responses indicated currently not doable. There is an open pull request for it though, so someone's working on it maybe

I really hate the "just google it" responses to questions online. Not only are they rude, they also actively damage the internet as a growing document. Even if you DO want to be an arrogant prick and say "you are a moron and google has the answer", you can do that AND post the answer. Whatever you post online is not a discussion in the moment but rather instantly becomes a part of the internet that will age with it.

Comments will sit forever unchanged, but google results will change. Oftentimes the thread being written in that very moment will become the top google result down the line.

The correct response to a question to which you know the answer, no matter how stupid it is, is:

Optional remark about how the OP should have googled

Single sentence stating the correct answer

A few sentences providing more detail, if more detail is needed

Link to the source, optional but recommended especially if the link has even more detail to read about and especially if you included the "you could have googled this" remark.

(this applies to matters of fact; opinions you usually don't need to cite etc)

If the link isn't to a self-archiving site like wikipedia, and you want to be really thorough, go to https://web.archive.org/ and plug the link into the "save page now" module on the bottom right -- that way if the page goes down or changes in the future, someone who finds the thread in the future can go to the wayback machine and see your link as it was when you made the post

In a similar way, proper etiquette if you post a question and it gets answered in the thread, especially if it gets answered in pieces in multiple replies, OR if you find the solution outside the thread (especially in this case), is to edit your post with a summary of what you found.
