Armorer Hannah Gutierrez-Reed failed in her primary duty to make sure weapons on set of “Rust” were safely handled. Asst Director David Halls failed to check the revolver before handing it to Alec Baldwin. But if Baldwin hadn’t pointed it at Halyna Hutchins and fooled with the hammer and/or trigger, no tragedy would have resulted. A 9-yr-old child would still have had his mother, and a husband would still have his wife.
