The involuntary manslaughter case against Alec Baldwin related to the 'Rust' movie set incident was dismissed after the judge found that prosecutors withheld crucial evidence linked to live ammunition brought in by a 'good Samaritan'. Special prosecutor Erlinda Johnson highlighted Baldwin's on-set 'horseplay' with the gun, suggesting it could be viewed as reckless, but clarified she quit the case due to learning about withheld evidence. Baldwin, who pleaded not guilty, was emotional as the case was dropped, with the judge criticizing the intentional withholding of information as causing harm to the defendant. Baldwin's defense, led by attorney Alex Spiro, focused on discrediting the police investigation and arguing Baldwin's lack of responsibility in checking the gun's contents.
