Im sorry, but in my minds eye, I take being neutral as not having an opinion of guilt nor innocence...He is asking her to be of mind that she is NOT guilty...
Not Guilty (at this stage) to me means, she is presumed innocent up and until she is proven guilty...which means something very different than what JB was suggesting. I do think the PJ gets what he was trying to do, as did JP and JA..
I dont know if DT wants anyone on that jury who is rational and common sensical..let alone intelligent sitting on that jury!!
