The difference here is that Baldwin was not a mere actor. He was a producer and the top dog in the entire process to film this movie. Dont think the "only an actor" defense is going to work
His dad was a marine, he grew up with firearms, has worked with firearms in many many films, and knew the rules. He broke rule #1. In the video of him "practicing" he drew the gun numerous times, and in every shot-his finger was on the trigger.
