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.
I was speaking in principle. Always walk away if you can from a group trying to antagonize you.
If he was not afforded the opportunity, then it’s self defense.
I saw the prosecutor video and it showed he could have walked away before the stabbing started. The two women were telling him to go away but he ended up punching one in the face. That’s when the chaos really started. People need to understand that you never know what will happen when you decide to get in a fight. A guy just got shot 18 times on the side of the highway. He got into an argument with another driver and both vehicles pulled off to the side of the road. They both got out of their vehicles and when they got within a few feet from each other one guy pulled his gun and unloaded it into the other driver. Just a senseless loss of life. One guy is dead and another is going to prison for life
