Absolutely correct, he can't lay it all at the feet of the person who handed him the gun. He has to always practice gun safety. Double check the ammo, put bullet proof plexi in front of camera operator, don't aim directly at the person behind the camera & make sure everyone else is out of line of fire. Clearly, multiple safety protocols were skipped.
Halyna Hutchins family needs to sue Baldwin, the gun armor, director & the movie company for millions.
This is likely murder & should be investigated as such. Possibly a Trump supporter loading live round to get back at Baldwin for his protesting against & many SNL portrayals of Trump. Or Hutchins may have been having sex with one of them & they were afraid of being exposed.
