Ft Worth police officer shoots woman to death inside her home

I wonder what happens in a situation like this if the homeowner only saw the officer as a silhouette with a gun and shot the officer dead.
Not inside a house, but rather a fenced in backyard.

I believe the guy ended up getting a 2 years probation after which his record would be wiped clean for some sort of low level felony.

Here Grand Jury did not find any evidence of a crime

here a guy was charged, but jury found him not guilty https://www.gunsamerica.com/digest/jury-exonerates-virginia-man-shot-cops-entering-home-mistake/
i rememebr reading that he eneded up getting a settlement from the city, but not sure.

This describes a few, including the case of Marvin Guy whose case is somewhat similar to McGee's (and in the same state) but Guy has been facing murder charges for 5+ years now. Looked for an update and could not find one: https://www.texasmonthly.com/news/a...-injuries-should-police-rethink-the-practice/
