I know you are well versed in the legal field and I value your knowledge but I am looking at it from a bystander's viewpoint (ie somebody who could well be a juror).
I think Galloway is not doing her best at the moment and I agree she should be intervening more but she may have more "up her sleeve" and by today's performance it seems she very likely has.
However Botha, to a lay person, appears to be doing everything he can to get a murderer off a guilty verdict. To me that is reprehensible. A good defence is always deserved, but arguing every point in minute detail the way he does, and is very well known for, shown by his historical success at getting murderers off, I find very irritating. That is, of course, why he is employed by persons very likely to be very guilty. I quite expect his expert witnesses will be 'in his pocket', much as we saw with Defence expert witnesses in the OP trial which is so very wrong. SA law has a long way to go to reach the standards of Australia and the UK.
