Of course you would.
They're both quite similar. If you know how to live your life in such a way as to be able to control the circumstances of self-defense situations to make ambiguous ones impossible then why not just live your life in such a way as to make any self-defense situation impossible? If you can control circumstances, why bother controlling the perception of ambiguity--just control the circumstances so you don't get attacked in the first place.
The point is that no matter how one chooses to live their life, there still remains the chance that they might be attacked and have to defend themselves. No matter how one chooses to live their life there's also the chance that the circumstances of a self-defense shooting might look ambiguous in retrospect. You want to know what prompted the deadly encounter in the aforementioned TX CHL shooting? A traffic accident where the defendant said he was going to report the accident. That's it. Someone hit his car and he said he was going to report it. Then the unarmed man attacked him and kept attacking him until he had no choice but to shoot since he could not retreat or effectively defend himself by other means.
Are you going to stop driving? Are you going to acquiesce to any demand put before you by an unarmed person lest they attack you and you be forced to shoot? Are you going to cease interacting with any persons unless you are sure that you could physically subdue them without resorting to deadly force? Do you know of some region where anyone with violent tendencies is stopped at the border and either not allowed in or they are given a weapon so if they do attack someone the circumstances of the self-defense case will be clear?
Reality is that you will get what you get. Just like the TX CHL shooting--you don't get to choose the circumstances ahead of time.
