If you are lying in bed with your partner and hear a noise, what do you do? I think everyone would first check the partner was lying next to them and then tell them they are going to check.
What did Oscar do, jump out of bed, get a gun with dum dum bullets go to the bathroom and fire 4 shots through the door.
I am amazed that the Judge discounted all the evidence from neighbours who said they heard a man and woman arguing. Also the evidence of Oscar saying they went to bed early, yet the contents of Reeva's stomach showed she had eating much later.
