...as well as the innate flaw with guilty/not guilty verdicts being decided by a Jury.
You'll need to expound on that remark as I'm unclear what 'innate flaw' you are referring to. Jury's can be sequestered by a Judge if the Judge feels that contemporary media coverage would be detrimental to their decision making. In this case the jury was not sequestered so it's safe to say that the Judge had no immediate concerns regarding jurors being prejudiced in their decision making. Also, all jurors in this case were instructed to ignore everything they had heard and knew about Rolf Harris and to just focus on the facts presented. So the jury was well aware all along not to bring in subjective emotion or bias into their decision making.
