Anywhere other than a movie set? Absolutely. There are people on set who have certain responsibilities. It isn't the actor's job to load the prop guns. In fact, they aren't allowed to.
I assume blanks are a combo of brass, primer, powder and some type of wad to hold the powder in place. So it would be easy to pull them and see if there was a bullet protruding from the end of the case but are the actors required to do that? IDK. They couldn't then, put the blanks back in the gun, though. Because that is the responsibility of the Armorer.
Besides, I'm pretty sure somewhere in this thread I highlighted a rule that required bullet proof shields to be in place to protect the crew in the event of a negligent discharge. Whose job was it to make sure those were in place? If it was Baldwin's then that's what they should nail him for.
