on more than one occasion talk directors out of using prop firearms that fire blanks
That sounds like extremely bad advice.
when followed properly everybody is safe.
Really, these guidelines would have prevented the use of real bullets allegedly mixed in by the prop supplier?
Making prop weapons do not have to be of inferior quality, and your argument that some may make live ammo for them would be extremely illogical if that was illegal.
If you want to use live ammo, what would be the argument for not using a real weapon?
If it’s some homemade shit, it would probably be pretty easy to spot anyway.
I stand by my original claim, which would 100% have prevented the incident. Even without training. You cannot reasonably argue that it’s safer that an actor should read and learn what 40 years of experience and numerous accidents have taught an expert, that he has written a book about. People make mistakes.
