If it’s during a scene, sure let’s break those rules. Once everything has been determined safe by everyone involved. Also yes, no matter who it is, I would expect anyone handed a gun to be responsible with the gun. I’ve never argued that other people aren’t responsible as well, just that Alec should be held responsible for his role. Let’s not forget that this actor killed someone, and he should face the same consequences that any average person would.
Sure that should always be the case. But this time it wasn’t. And because of his actions someone died. As an actor and a producer he should never have even had a chance of firing a live round while they weren’t filming, but he did. If the round never hit anybody this would be an entirely different case, unfortunately that’s not how it went down.
