I suspect the contents of the loo bowl wouldn't stand up to much analysis.
YY Nerf iirc they stated early in the trial that because Reeva fell onto/over the toilet bowl, they couldn't analyse the contents as there was blood, etc.
I think OP has had support from people across the globe including all those supporters who used to turn up at court for autographs and photos
so I don't think badly of him for thanking them.
As for Franck, I do wonder if there are people who have heard his story and do know what actually happened that night. I remember a friend who lived in an area where a crime was committed and it was common, local knowledge what had happened, where the weapon was hidden, etc, but everyone was too frightened to go to the police to tell them. tbf the local community couldn't understand how the police didn't know when everyone else did!
