However, this most recent confirmed information that the victim pointed a handgun at the officer, confirms my hunch that the officer was merely negligent, and did not commit a crime.

Suppose the defending homeowner had been a little quicker on the trigger, and shot the intruder before he shot her.

Would you consider that "merely negligent", or would you be damning her as a "cop-killer"?

Im this state, as in most, the courts take the position that you can not plead self defense if you are in you home and the bad guy is still outside your home.

Many a person has gone to jail for shooting through the door (outside door) at a person who has not yet breached the door.

So the answer to your question is that she would have been tried and convicted in almost all states. Texas is different and a Texan will need to answer for Texas.
