Again, he didn't shoot the guy who fired nor is it his sole justification for shooting Rosenbaum. You're arguing, for a third time, against a point that wasn't made (no one claimed he was justified simply because a gun was fired) and are being especially silly in doing so when it's been answered/pointed out twice already.
Yes but why? you don't seem to be able to explain why? You just repeat the assertion and keep it vague/are incapable of actually articulating your point.
re: the first claim, you've now claimed twice that the firing of the gun was in a completely different area - this is again because you've clearly not watched the footage, the screen shot below is misleading and is perhaps the source of your confusion here:
This is why you're wrong, it's illustrated clearly in the video below if you skip to 4:40
Here are some key screenshots:
The Ziminskis circled in red, Mrs Ziminski clearly pointing ay Kyle (circled in blue) and Rosenbaum (circled in orange) immediately gives chase:
Rosenbaum chasing Kyle:
Mr Ziminski walking along right behind them firing a gun into the air:
You claim that gunshot had nothing to do with Kyle, that, in your words, "The gun was fired in a completely different place to the chase", "was made elsewhere to the altercation between the two." etc.. when that is clearly false, it occurred seconds after the person who fired the gun and his wife had just pointed out Rittenhouse to Rosenbaum and they were following directly behind him!
