"Moments before the fatal shooting, Assistant Director Dave Halls grabbed a prop gun off the cart and brought it inside to Baldwin, unaware it was loaded with live rounds, detective wrote in the application."
Okay, what's "loaded", six rounds ? What are "live rounds" ? Live blanks, live fixed conventional (real) ammo ?
So the armourer and assistant director handled the gun before idiot Baldwin, bring them up on charges...."here's and empty cold gun, you're ready to go buddy"
