Hollywood's rules were broken if "Rust" assistant director handled the gun before deadly shooting, armorer says

Santa Fe County Sheriff's Office deputies recovered loose ammunition, ammo in a box and in a fanny pack on the set of "Rust," according to court documents. It's unknown what type of ammunition was recovered. 

Some in the entertainment industry are calling for a halt on use of real weapons in light of the shooting that killed cinematographer Halyna Hutchins and wounded director Joel Souza. Hutchins was killed after actor Alec Baldwin discharged a prop firearm on the movie set. 

ABC's cop drama "The Rookie" announced it will stop filming with live gunfire immediately.
