It still took 12 hours of deliberation for the new jury to reach a verdict. That's astonishing. 40 years ago, it was unheard of for a jury to take 12 hours for anything and "overnight juries" were almost unknown.
Are modern juries infected by the disease of indecision? Do they have no decision of importance in their own lives when they are confident enough to say yes or no, and that's final? Or have they got a committee mentality, where no individual dare decide anything and the body as a whole would really like to put the decision off to another day?
