I don't know, but did I take guns off of people in 'odd' situations? Sure. Was it absolutely necessary? Probably not, but yes, if I'm the LEAST bit nervous and you have a gun, guess who is giving me that gun, nice and slow? Not even moderately thinking of apologizing for it. Once the situation was diffused, the person was either arrested, or got their gun back, end of story. Didn't have to worry about the gun being involved.
You may call me a JBT, fine, go ahead and Walter Mitty the situation. But if you have a gun and I see your hand go to it, bad things start to happen. I know human behavior, it's natural to rest your hand near where you put your gun, it's why you put it there. It'd be a little different if more people ankle carried, but most people don't.
