Ok.
I don't believe it is reasonable to believe in this sequence of events.
1. Pistorius grabbed his gun under the bed, yet could not confirm Reeva was on the bed, when he would be right next to her
2. I do not believe any reasonable person would hear a sound in the bathroom and not consider it is the person sleeping over
3. I do not believe Reeva would be at the door of the toilet rather then sitting on the toilet, unless she was in fact talking/arguing with Pistorius, because usually you go to the toilet to use the toilet, not the door, on the other side.
4. I do not believe Pistorius could aim so well, in such a sequence, first knowingly being able to hit Reeva at the position of the door, which requires knowing she was at the door,
instead of the toilet, then adjusting his aim to shoot at her fallen body which then fell on the toilet, instead of simply backwards from the door.
Given Pistorius' well known history of verbal abuse, both publicly in front of his girlfriend, and privately, it is clear and fact that Pistorius is mentally unbalanced with regards to relationships with women.
In that regard, nothing is outside the realm of reasonable possibility in his abuse of women.

I am just taking off on this point, Vantos, though I agree with everything you said. I have been working for a while, in 3D, on recreating some of the sequence of events on Feb. 14. I have done an animation recreating the actual shooting. I am not very good with animation. I have feet going through the floor, a hand going through the toilet, my camera work sucks and the timing is off here and there, but this is more or less what I think happened to Reeva in the WC. Op's figure is not animated except that I moved him backwards down the entry while he is firing as was shown in the Sunday Night video. I posed him as he demonstrated his shooting position, also in the video. He clearly could not have made most of the shots as he moved backwards in the entry.
I know the exact heights of bullet A (depicted in red) and B (depicted in green). I used the heights of the bullet holes in the door for bullets C (blue) and D (yellow). They would actually be a little lower because of the 5 to 6% downward trajectory, but I don't know how to figure that. I know where B hit the wall. I was surprised at how high bullets C (blue) and D (yellow) were. I got some clues about the bullet positions from the back and forth between Wolmerans and Nel during cross. He said that one bullet probably would have hit the short wall, probably A (hip shot). That helped me position A in space and helped with Reeva's standing position. B (missed shot) is known to have hit at mark E in the corner of the back wall and the short wall. He said that one bullet would have hit close to the bullet ricochet marks E and F. I have decided that bullet C was the third shot. I can't be absolutely sure, but it seems to be most likely to me. So I positioned bullet C the (arm shot) close to the ricochets. This meant that Reeva had to be a little higher than she would have been had she been sitting on the magazine rack at that point. I am the least sure about the position of bullet D (head shot), so did the best I could with that one. I positioned it where it could have caused the blood and tissue on the toilet lid.
The animation starts with the hip shot. She falls backwards with weight still on her left foot and with her back against the wall. She balances there, on her left foot, using the wall to stay half standing for a very brief time, just long enough for bullet C to hit her in her right arm. Her right arm drops. She drops onto the Magazine rack. She tries to cover her head with her left hand as she continues to fall towards the toilet. Bullet D hits her between her fingers and in the head, as she is falling. She ends up with her head on the toilet bowl and her lower body on the magazine rack.
I want to do an animation using OP's version one of these days. I am really glad that someone leaked the video as that will help me a lot.
