It seems that Alec Baldwin is producing a film, "Rust" and someone was killed on the set due to what the media is calling a "prop gun".
Sounds to me that something went terribly wrong.
The Santa Fe Sheriff’s Department confirmed Thursday night that Alec Baldwin “discharged” the prop gun that killed Rust cinematographer Halyna Hutchins and injured director Joel Souza on the set of the Western feature film on location in New Mexico.
Wow! Accidents happen. Early reports are often wrong, and it would be futile and insensitive to speculate at this time. All guns are dangerous. Hollywood has a long history of using guns on a set and I'm sure that there are many safety rules, with multiple people responsible for the safety f the crew. But, ultimately, the responsibility lies with the person who was holding the gun at the time.
All guns are always loaded.
