Alec Baldwin Shooting

[slartibartfast]

Rule #1 of guns - when you pull the trigger - you own the outcome. Period.  Only self defense or the defense of others is a valid reason to shoot someone.

Sure. So by your reasoning if a child gains access to an unsecured gun in the home and accidentally shoots someone, then they are guilty of manslaughter. Period. No exception. Got it.

Does your rule also apply to where actors are told that there is no petrol in the tank when they are supposed to throw their lit cigarette in to cause a delayed CGI explosion, but instead someone filled it up with gas and they blow up the entire set and everyone in it? Of course not. 

Or how about the scene where they throw someone off a cliff and the safety net below is not secured properly? Is it the pushing actor's fault for not double checking that this is safe? No. It's the crew's responsibility. 

How about the actor who hands another actor a poisoned glass of wine - but instead of being benign, this really does contain poison. Is it the actor's fault and he/she should face manslaughter? 

Why should a gun which was provided with the clear instruction that it was not loaded be any different to any other piece of potentially fatal film equipment, but in your opinion come with different responsibilities attached?
