A right muddle...
If you hire Barry Roux to defend you on a murder charge, you hope that the forensics expert he employs will know his stuff, but more importantly will not contradict your story on the stand.
It appears that Barry's forensic "expert" didn't get that message, nor does it appear that he knew an awful lot about the technical details of that fateful evening - a bit like Oscar although we all know Oscar isn't telling.
Possibly the clue(!) is in his profession - forensic GEOLOGY which according to Wikipedia "is the study of evidence relating to minerals, oil, petroleum, and other materials found in the Earth, used to answer questions raised by the legal system." So if you want to prove that somebody crossed a certain piece of ground to dump a body, you might employ a forensic geologist to analyse soil samples taken from the suspect's shoes. Last I looked Oscar didn't have any shoes on - in fact he didn't have any legs on either - so that line of enquiry is out. (Okay that's a bit offside - apologies to Mathwtwhe Mumbaza from the ANC League of Women).
And then to add insult to [censored], the geologist couldn't get his facts straight and ended up contradicting the very person he is supposed to be helping to defend. No Oscar awarded for this performance!
Oscar now has two weeks to go away and lick his [censored]. His hope must be that the next "expert" that Barry puts on the stand realises he is giving evidence in the Pistorius trail - and not Shrien Dewani's!
Out.
