Quality over quantity, for trails of this severity you have multiple judges decide the case. I am not convinced that having a random selection of people with no experience in law results in more accurate verdicts, in fact there is plenty of evidence of the opposite.

I'm supposing then as part of this restructuring of society that will never happen there will also be a restructuring of how judges get to be judges in America which will also not be happening so that this "quality" will be achieved.

You don't have to set the quality bar very high to get someone who is better at deciding a verdict than the average juror.
