The #1 rule of firearm safety that I learned as a child was "Don't point a gun at a person.". The corollary to that was " Don't point a gun at anything you don't intend to shoot." There is also the rule that if someone hands you a firearm and tells you that it's not loaded, you should OPEN it to make sure they really had checked it for ammo before they passed it to you. I know Baldwin is very anti-gun, but being anti-gun doesn't excuse a person from knowing basic firearm safety. The armorer who got the 18 month sentence was a scapegoat. She had little experience, and that was likely why she was hired for that job. She could be pushed around to do what Baldwin wanted. There appear to have been many opportunities for live ammo to have introduced onto the set. Those should have been eliminated. This incident should never have happened.
