I've poured through SA's rules of criminal procedure but can't ascertain whether they actually have reciprocal discovery or not. State's obligation on discovery is very clear - defense, not so much.
For me the most fascinating difference is that it doesn't matter legally if he intended to kill Reeva or an intruder as long as intent is proven itself. Makes a heckuva change from castle, SYG, and other domiciliary defenses with which I'm familiar.
That's not quite how the law or intent reads to me, speaking of SA law, specifically.
