Hmm good question. I had a nice view today, could perfectly see KK, PF, and Jury. I noticed them looking at PF quite a bit. Who really never looked up at all. Saw him look up once.
KK would say a pretty "interesting" thing and I notice them all glance to see a PF response. Of course he didn't give one.
It's hard for me to actually see if they are making any facial expressions or what not. I really can only get a good look at the 4 or so closest to us. Some seem to be very deep in taking notes.
What sucked was, when KK tells us KB's final words, she immediately bolts from the stand and has police escort her out. This blocks me from seeing the jury, thus I could not see their initial response to this.
