Before the trial is over or post trial, I think there is a difference. In other words, if somebody, post trial, consults the services that are available with mental health professionals for counselling, I think that information would be regarded as confidential. The distinction that is being made is between talking about their experience, if it were stressful, for example, during deliberation, versus the issues that are off-limits, which are the processes and content of the reasoning for the decisions for the verdict.
