P.F.W. Dueling Pistol - Left View

What I'd really like to know is what a real gun was doing on stage in the first place? Even more importantly, is why was it LOADED with live ammunition? From the damage that the bullet did, it had to have only been a .22 caliber pistol, but that's beside the point. Was the actor that shot him brought up on charges of attempted manslaughter or the stage manager (or whoever was in charge of props) charged with conspiracy to commit murder? It doesn't matter if the actor thought it was a prop gun or not. Both of them relinquished all excuse of naivety by failing to inspect the "prop" correctly before taking the stage. As a maker of prop guns, I understand that the goal of all prop designers is to create a weapon that appears to be an accurate representation of a real or imagined weapon. However, regardless of how real it looks at a distance or up close, if someone were to take five seconds physically handling anything but the best prop guns they would realize that they are fake.
