If you have a chance to walk away, it’s always best to do so.
I didn’t see him being given that chance, from the video clip. They had decided that he was peeping on the girls, & nothing was going to dissuade them from that belief. The option to walk away is one that is available for both sides, not just one side only. They surrounded him preventing him from doing as you suggest. The fact that you fashioned your response as you did; If you have a chance, indicates to me that you are unsure yourself if he was actually afforded that opportunity.
When it happens to you, be sure to just walk away from greater numbers shoving you down to water level.
People here have taken time to watch the extended video out on telegream? It paints the complete picture.
