How could it be possible that he couldn't see it could be his girlfriend in that bathroom? It seems to come naturally that when you have someone else with you home his existence would be something you account for everywhere you go in that house and especially for a place like a bathroom. Are we talking about an adult here or someone acting like an infant enjoying watching a person appear and disappear from behind an object because it forgets about what it cant see even if it is still in the same place with it?

And assuming it did not occur to him that it could be his girlfriend from the onset, how is it possible that such possibility was not revived after firing the first shot and make him think what have I done before continuing to fire the rest of the bullets? That seems to make the continuing with the shooting like the starting of the shooting both fit good with trying to take advantage from the inability to see what is behind the door. In addition to that we should also assume that no sound came from the victim until he finished shooting. 

Look at the "INTERACTIVE" part HERE.What person having another person with him in the house, let alone someone like him living in a gated housing complex with security, hears a sound in the bathroom and not only the first thing but also the only thing that comes to his mind is that it must be an intruder (#2) not the other person with him in the house? Moreover, isn't the action of opining a window fits with that of bringing the two fans in that both related to the need for cooling? Notice also that it seems he had to pass on the bed while going to from #1 to fire on the bathroom?

Anyway, aside from all that, even if we assume that the intruder defence which seems to be like a joke is true a question still remains about endangering the society by a person who lacks the capability to make a correct judgment to this level. If you fail like this in making the correct judgment here how can you be trusted on the life of others with, for example, driving a car?  Shouldn't it be that the same lack of correct judgment that gave you an excuse here also take the same level of your rights like a normal person to be trusted on things that could affect the safety of other people? So even if we assume honest intention, imagine how much that claim could take from other rights? If you make judgments like this then is it safe for people to allow you to even just walk among them or neighbor them?
