"In order to make it fire, you have to put your thumb up onto the hammer, *advertiser censored* the hammer all the way back, and then as the hammer is completely cocked back, then you pull the trigger and then the gun fires," [armorer] Carpenter explained. "So that's very important because that gun had to have two step process to fire. It had to be cocked and the trigger pulled to fire."

"Once you *advertiser censored* the hammer back on one of those old west guns, it doesn't take a lot to set that trigger off," he told Fox News Digital. "You know, they're very light triggers."
The modern-day Glock handgun has around a five-pound trigger pull, according to Carpenter, "whereas one of those old westerns could have a two pound trigger on it, which is half or less than half of what a modern gun has," he said.

Film and prop historian Michael Corrie explained to Fox News that firing a revolver without pulling the trigger would require a "mechanical failure."
Alec Baldwin's claim he didn't pull trigger on 'Rust' questioned by sheriff: 'Guns don't just go off'
Short of the FBI determining the gun really did fail mechanically I'm afraid enough people will be swayed by the claims made by Baldwin and others, true or not. Did Baldwin explain why he pointed the gun at Halyna and/or her camera?
IMO HGR is still the center of responsibility: without her sloppy handling of the gun and ammo Halyna would be celebrating the holidays with her family. HGR can deny and deflect all she wants but it won't change the facts. MOO.
