In the hours before Thursday's fatal shooting, members of the camera crew left the set in protest against the safety of the production and poor working conditions for the film in which Baldwin is credited as an actor and producer.
“They did everything they absolutely could to save a nickel at all costs,” a source told the Daily Beast . “They put everybody in jeopardy in one way or another, whether it was hiring less than qualified people to deal with firearms or it was the constant fight about housing people appropriately. In all my years of doing this, this is one of the worst productions I’ve been on.”
The person in charge of prop firearms the day of the fatal shooting was an armorer named Hannah Gutierrez Reed, according to a call sheet for the film reviewed by the Wall Street Journal . Reed, 24, had recently worked on Nicholas Cage's movie The Old Way as the head armorer. It was her first time being the head armorer, though her father was well known in the industry and trained her on firearms and props from a young age.
