Isn’t it amazing how we had westerns galore (both tv and movies) in the 60’s and innumerable crime shows and movies in thee 70’s without any of these types of incidents.
But those on the sets were likely veterans and had respect for guns.
The needle on my Schadenfreude meter got pegged so hard on this one that it broke in half. Banning guns on movie sets would put Hollywood out of business in about a year
