Celebrities are among the class of Americans who are usually above the law. Don’t expect him to be prosecuted. I don’t really blame him if he was given a gun and told it was “cold”. He should have checked for himself as a failsafe, to back-up the person who handed him the gun.
When I rent a car and the employee tells me the tank is full, I always check for myself. I don’t assume he is right or honest.
Baldwin was negligent in not checking for himself if the gun was empty. That said, he isn’t to “blame” for the death. Someone else in the chain of custody is to blame. That would be the person primarily responsiblel for INSURING guns handed to actors are empty when they should be empty. Just IMHO.
Baldwin should be civilly liable however, as a producer of the movie.
A reasonable investigation would necessarily ask the questions “Did Baldwin know the gun was loaded” and “Was this a conspiracy to commit murder.”
