I'm glad you wrote that Gobbolinothewitchscat since it seemed to have become a given that OP would have been "coached" in the story he told.
Yes - I think this is why we have had a few instances of OP "blaming" his lawyers for things on x-exam. I recall one specific instance re his evidence in the bail affidavit
I think OP seems to think that they should have "stopped" him or encouraged him from saying certain things. But that's not their role. That said, this should have been made explicitly clear to him (in writing if needs be) and they should have obviously questioned him very carefully to make sure they could advise him properly
I think OP should definitely have pled guilty to the gun charges - idiotic not to and it's allowed the prosecution to introduce character evidence re his attitude to authority/temperament and guns that they wouldn't have ordinarily been able to. Plus, he looks like a liar saying the gun in the restaurant just went off in his hand. This is a man who - on undisputed evidence - carried a gun with him, on his person, every single day (bar travelling abroad, one could hope). His refi illite has been very seriously affected on quite minor charges. Plus, his barrister could then have said: "Hey, this is guy who tells the truth. Right away. No messing about. He's pled guilty right away. He knows he is in the wring. I give no don't he would have done the same with the other charges"
I do believe that OP will have been given advice to plead guilty to the culpable charge and show complete remorse. Which you can do relatively easily. Even if you don't feel too bad about Reeva. Then the thought if being bum raped in a South African prison fir 25 years is enough to make even the most hardened psychopath cry. Plus, it's quite hard for Gerrie Nel to attack that kind of evidence as he can't get in to the meat of the case as OP has pled guilty. End of. His evidence, in totals, could have been over in half a day.
I think, if he had done this, he could have had a round about 50% chance of getting a suspended sentence.
But he's not and is risking absolutely everything on not being found guilty of murder and the judge finding him not guilty on the lesser charges. To do that, he would have had to play a blinder in the witness box. Which he's not. So he's fucked. He'll definitely get time for the lesser murder charge - I think 12 - 15 years
