I might be wrong, but Title 21 § 1289.25 is the only section of Oklahoma statutes that I recall deals with Stand Your Ground situations.* I don’t see any mention there of running away, fleeing, escaping, etc.
So, just to make sure I understand your position, you would not think it justified to use deadly force against someone who is running away from you while pointing a gun at you or even shooting at you?
* Obviously the incident in question didn’t happen in Oklahoma. I’m not very familiar with Castle Doctrine or Stand Your Ground in Texas.
If you want to change the situation, then ok. But that wasn't what was being discussed, wasn't what was mentioned in the article, and wasn't what you yourself said.
