I am a believer in professional juries too. JMO
I've thought about that too over the years.
But I'm worried if professional jurors each think they are more intelligent than the others then very big egos could definitely get in the way. Especially if there are differing points of view on the same evidence.
Remember in Scott Peterson's case? Imo the first foreman felt he was far superior in intellect than the other eleven jurors. So much so he would only deliberate HIS way or NO way. Imo, his ego got in the way of common sense. Professional jurors may also have big competing egos.
Honestly jurors have been rendering correct verdicts in courtrooms everywhere since we started having juries. and only gets it wrong every so often.
I personally still trust juries who does take their duties seriously, imo.
Now what I do see popping up more are the lone wolves, but that could happen with professional juries as well who refuses to budge.
Sometimes I worry that lone wolves are doing so in high profile cases because it sells more books to go against the grain than with it.
I think we'll have an unanimous verdict in this case though. I can't see a lone wolf being strong enough to go against the majority. The stakes are too high, and they know what the city has already adversely gone through even before the trial.
