During the ongoing trial related to the fatal shooting on the set of the movie 'Rust' in 2021, defense attorney Alex Spiro has raised arguments regarding the difficulty in distinguishing live ammunition casings from dummy ones, unless one is an expert in the field. Spiro presented photo evidence to witness Marissa Poppell, a crime scene technician, showcasing the live ammunition and dummy ammunition found on the set at the time of the incident.
When questioned by Spiro, Poppell acknowledged the significance of the presented picture. Spiro pointed out the resemblance between the live round and the dummy round provided by Seth Kenney, the movie's gun and ammunition supplier. Poppell conceded that under a camera flash, the two types of casings could appear similar.
