I frankly don’t agree with the if you pull it use it theory. Twice in my life, not at work, I have had to ward off a problem with a firearm. Both times the individual stopped doing what they were doing immediately. If I could avoid blowing someone away, I was happy doing that. BTW, in neither of these situations was my life in immediate danger although I could legally argue it could have been if I let the situation go further.
From the movie “Big Jake.”
John Wayne and company are riding into a rough town with a large trunk full of money, guns up and ready.
Duke: “They all know what’s in there and they all want it. What we’re doing with this ostentatious display is telling them they can’t have it. Who knows, we may be saving some poor miscreant’s life.”
