Alec Baldwin Shooting

[Spongebob]

Of course it matters. Context is everything. It's the same as saying if I drive my car in the real world I am responsible for the safety of said car. Which is true if I am the owner. If someone hands me a car (such as, say on a movie set) and asks me to drive the car for a scene in the movie, the car then has faulty brakes and I run someone over would you then say "well you were driving the car, you should have checked the brakes". 

Which in the scenario of acting is of course, ridiculous, as the responsibility for making sure any equipment I am supplied on set by my employer is fit for purpose, and works as described. If Baldwin had brought his own gun to the set, then you would be right, however you are not. 

If I am doing a scene with a realistic looking - but soft - rubber knife and I have to convincingly stab someone, but the assistant hands me a real knife instead, I am not to blame.

So I think your ideas are completely fucked up.... and I am glad I don't live in your world. 

BTW. You calling me Jesus should be slightly offensive to me as an Atheist? 

Does ANYONE check the brakes on a rental?
