It ended well, and the coverage was surprisingly very good, however she did some things wrong:
She re-entered the house, unless she had some reason to believe that there was some reason for someone to legally be in there she should have stayed outside the house, and took cover behind the engine block of the car, or other suitable cover while observing the house, and called 911, she is not an entry team, nor did she have anything personally at stake.
She hung up on 911, she should have been on the phone with them the entire time, even if only having the line open with the phone in a pocket, the reason being that 911 calls are recorded, and if she had to fire, it would be documented as a justifiable shoot.
She did not break concealment even in the house, she should have at a minimum had the revolver out, and at a low ready, though a high ready would probably have been more appropriate.
She carried out a conversation with the intruder, you never, ever do that, it lowers your guard, and increases the intruders confidence. Her dialog with the intruder should have been limited to screaming commands at him, specifically "STOP, GET ON THE ******* GROUND DO IT NOW!!!!! I HAVE A GUN, AND I WILL SHOOT YOU!, SPREAD YOUR LEGS, AND PUT YOUR ARMS OUT, SPREAD EAGLE,PALMS UP! CHIN ON THE GROUND!" If he attempted to say anything she should have simply yelled "SHUT THE **** UP!!!!!" The idea is to assert dominance, break auditory exclusion, and remain in control.
