Cool, first year law courses. Come back when you’ve spent years doing tactical training. The only more escalatory thing the YouTuber could have done is actually hitting them. At which point it’s too late. We don’t live in Hollywood land where the bad guy stands back to let the hero do whatever they want. Court rulings generally support this unless the state is a duty to retreat state. But Virginia is a stand your ground state. (As are most states these days)
What the YouTuber did is colloquially called Bulldogging and the entire point is to intimidate someone with an intimation of physical threat.
