Alec Baldwin's involuntary manslaughter trial regarding the shooting death of cinematographer Halyna Hutchins on the set of the film "Rust" took a surprising turn when his defense team filed a motion to dismiss the case due to disputed ammunition evidence. Attorney Spiro argued that prosecutors withheld evidence related to the ammunition, which could impact the case. The film's armorer, Hannah Gutierrez-Reed, was set to testify but the trial was delayed. Gutierrez-Reed was previously convicted of involuntary manslaughter. Prosecutors claim Baldwin skipped safety checks and mishandled a prop gun, leading to the fatal incident. Baldwin faces 18 months in prison if convicted. The trial includes witness testimony, including a 911 call and bodycam footage, showing the aftermath of the shooting. Baldwin has maintained that the rules of firearm safety are different on a movie set.
