[Double Naught Spy]

Interesting case. The appellant did so many things wrong.

The Appellant intervened when it was unnecessary (others had calmed Decedent)
The Appellant forced the situation unnecessarily.
The Appellant upped his game when his "authority" (badge) was rejected and brandished with the intent to intimidate.
The Appellant was much too close to the Decedent and upon upsetting the Decedent sufficiently, the Appellant was punched.
The from a safe distance away, the Appellant drew and fired his gun, killing the Decedent.
The Appellant made claims in court that were not backed up by witnesses and there were a lot of witnesses to the event (church full of hundreds of people).

So the Appellant seems to be a self righteous hothead who tried to exert authority he did not have over the upset decedent who defended himself from the Appellant after the Appellant brandished.

As for flashing the badge, it failed to have the desired impact. That has happened with cops before as well.

Blathering? Didn't help. Given the witnesses present, I don't believe the outcome would have been different, however. No doubt the state called plenty of witnesses during the actual trial.
