I'm not arguing legalities here, just common sense. When talking with a cop while wearing a visible and immediately deployable weapon, rule one is to separate yourself from the weapon. Then have the conversation. It turns the volume down by many notches. Its not like you're going to shoot the officer, but he doesn't know that, and this lets him calm down as he is no longer concerned. If he wants to arrest you, he will, but its a PITA, not the end of the world as you were cooperative, within the law and on tape. But in Texas, I doubt it would have gone even that far. It was just two type A personalities meeting, neither showing any common sense and the guy with the badge won.
