I have eyes, however.
You should let your wife/girl friend know that she can be harassed in public as you stand transfixed.
And you are really good at projecting.
Setting aside the legality of the shooting, one wonders why the boyfriend could not have reacted with a bit more shame and humility. You know, like maybe “I’m sorry we parked illegally. We were in a hurry and it was just for a couple of minutes. We won’t do it again.”
Actually, I don’t wonder. It was because he was disrespected and the cracker had to pay. The couple escalated the conflict and he wound up getting killed.
I had a similar thing happen to me recently, even more trivial. I really wanted to punch the dude but I settled for verbally insulting him the best I could. You never know where a physical fight might end up. Neither I nor this guy were in any danger. I kept me cool, this guy didn’t.
