Do we know for a FACT that GZ was not brandishing said gun?
Ironically, were I to open carry where anyone could see my weapon, that's 110% legal. Were to carry concealed and, in a conflict, even show that I was carrying, that's brandishing and considered assault. So, if I were to carry and my shirt accidently gets pulled up over my pistol and someone sees it and feels threatened, I have just magically commited assault. Another reason I rarely carry despite the fact I am licensed and trained to do so.
