That is a pretty rough stance to take. A woman, or a younger person, can't be relied upon to do the job they held themselves out to be able to do? I agree that whoever hired her has some questions to answer. But it could very well be that they felt they needed to hire more women.I have to say that I do feel sorry for her. She clearly had a very intense, safety critical job to do and wasn't capable. Part of the reason she wasn't capable, I think, is that she had no support or assistants to help her in the role. She was waaaay out of her depth!
There is no way she should have been in sole charge of a firearms-heavy production with her level of experience. In that sense the producers (employers) are to blame because they are hiring unsuitable people and providing inadequate resources for her to do her job.
This is probably an extremely uncool and un-pc thing to say in this day and age but - she was a 24 year old woman working amongst massive male celebrity egos with zero support and probably with little confidence shown in her ability. Yes, she should have had more control and should have been with those guns everywhere they went but that's very easy to say from our detached position. Is it any wonder that this whole sorry situation played out as it did?
