A defense attorney says that Alec Baldwin's shooting of a cinematographer was “an unspeakable tragedy,” but that he “committed no crime, he was an actor, acting.” Baldwin's attorney Alex Spiro gave the opening statement Wednesday at his involuntary manslaughter trial in New Mexico. Prosecutor Erlinda Ocampo Johnson told jurors Baldwin “violated the cardinal rules of firearm safety” in her opening. The trial will delve into the confluence of gun safety, high-wattage celebrity and a low-budget Western movie on a remote movie ranch. Baldwin was the lead actor and co-producer on “Rust.” He has pleaded not guilty and says he followed instructions in pointing the gun and didn’t pull the trigger.
