Being confident is not the same as gossiping. No details discussed at all.
It is absolutely not a witch hunt, it is a criminal trial.
Sounds like bollocks to me.
I doubt very much anybody who is genuinely involved with the trial is going to say one way or the other in the first place. Secondly , if someone close did give an opinion , it's unlikely they would say they thought the case was shaky. If that got to the media , that the crown thought the case was wobbly, then it would certainly cause trouble.
