Crew on Baldwin film raised prop gun concerns before fatal shooting

Text message warning of super-unsafe' conditions was later followed by a walkout by camera operators

A picture of chaos and concern on the set of Alec Baldwin's new western, Rust, has emerged from fresh accounts of the lead-up to the fatal shooting during filming on Thursday.

Only days into the three-week production schedule, new reports suggest that a worker had been so worried about weapon safety he had sent a text message to his manager warning of super-unsafe" conditions.
