If someone hands you a gun, unless you saw them clear the gun of any bullets & other obstruction you should check the gun yourself. Also don’t point the gun at anyone and keep your finger off the trigger.The gun was loaded by the armourer or an assistant and handed to Baldwin. He has no obligation to check it. It's supposed to have just been checked.
It's possible for a revolver to fire without pulling the trigger.
This topic has been done to death in previous threads and I was going to just miss this one. But you guys are making silly mistakes on basic facts.
Regardless of Baldwin, just responsible gun use.
