Botha's losing people's respect I think, he's actually reversing the situation because the more he badgers these witnesses, it magnifies what the truth is, there were no intruders, HvB is the attacker and his superficial wounds are self-inflicted. It's not working a charm like with the police and security staff.
The police are always soft targets for the defence in criminal trials because they nearly always do something wrong, not just in SA. They're so poorly funded in SA and don't get the training that's needed. There are 2 things that would solve a lot of their problems though that don't require much funding or training.
1. Officers attending a crime scene, in particular where murders are concerned, should videotape everything and have another officer oversighting this.
2. When suspects are taken to the station to be interviewed, 2 officers should be present for the entire interview and it should be audiotaped.
