In those two trajectories just shown, green and blue, downward trajectory IMO would tend to support that the victim was below the shooter AB, and perhaps cowering or attempting to evade or avoid. Possibly even get around that wall or corner in the room? And seems also IMO that the defendant, AB, was in full control of the matter at that point when firing the gun those multiple times. Four shots eh?
And witness just said that multiple different points of entry differing locations, the victim was attempting to move or adjust position. That also sounds like he is trying to avoid IMO. Not threatening. MOO
