Pretty much everyone the State has called has come across as more credible and having more integrity ultimately than the Standers. Ultimately* the Burgers did the right thing.
Moving on to the forthcoming Weskoppies evaluation I wonder if some of OP's associates ( as opposed to his family) will feel - outside of the pressure of a televised trial and beyond Oscar's jaw-clenched cold stare- they can be a little more impartial?
I'm thinking of his coach Ampie Louw and agent Peet van Zyl who will surely be called for interview by the psych panel. If OP had had longstanding GAD they would have seen the symptoms. Equally they could recount many instances which link to NPD/APD. Or, is everyone going to lie? ( Which links back to my initial Burger point.* Even if one can't do the right thing initially..... there's often an opportunity later.) Although I perceive that OP has a difficulty with remorse, still hope that others who know him well might have reflected and be honest in their interviews.
I'm not saying van Zyl/Louw will push him under the bus now that OP is no longer an income-generating asset. That would be too cynical. But according to sports reports OP and Louw already "had planned to give up track together after the next Olympics and Paralympics in Rio" in 2016.
