Alec Baldwin's involuntary manslaughter charge related to the Rust shooting incident was dropped by a New Mexico judge after his defense team argued that prosecutors withheld evidence, leading to a dismissal with prejudice. The evidence involved live ammunition turned over to authorities, suggesting it came from the prop supplier, not the film's armorer convicted earlier. The judge's ruling followed dramatic proceedings where the defense highlighted the concealed evidence, prompting the case's abrupt dismissal and emotional reactions from Baldwin and his family. This decision could potentially impact the release of the convicted armorer, Hannah Gutierrez-Reed, from prison in New Mexico.
