Just wanted to clarify some things posters are asking about with regard to the position of the duvet.
As I understand it it is important to support OP's version of the police moving things, etc. If the duvet and jeans were as depicted in the photograph taken at 0548 (I think) then the upright fan could not be where OP states he put it after bringing it in from the balcony and closing the doors. The siting of the fan is crucial because if it was where he says he put it then it corroborates his version of having his back to the bed and therefore not seeing Reeva get out of bed, essentially the duvet on the floor stops the fan being where he said he put it, and the duvet couldn't be where it is in the photo if OP had put the fan where he said he did. Also in the position in the photo the fan impedes access to the windows for him to open and shout for help. If, however, the police moved the fan and threw the duvet on the floor and the jeans on top to discredit his version of events why would they do that when they were at that time unaware of his version of events. It is one of those details that casts doubt on the scenario OP has given.
I thought Nel made mincemeat of the defence expert today, I saw Roux visibly cringe at one point in the testimony I think if he could have put his head in his hands he would have. Also, when the Judge told Nel off she had a slight smirk on her face, and at one point she seemed very annoyed with Mr. Dixon's lack of expertise. I think it is rather disrespectful to the court to produce an expert witness who is clearly no expert, and admits to not being one, and having him make pronouncements on subjects he is not qualified to.
An SA legal expert was saying on Sky News that he thought Roux might cut down the number of defence witnesses he calls due to the mauling Dixon got today.
