I think that the letter written to the judge about juror #5 was Plan A from a Jodi supporter to get juror #5 kicked off the jury. Whoever wrote the letter (and I wonder if they had the support of the defense team, or Jodi herself to do it) tried to make it seem like the letter was being written from an anti Jodi person. I don't believe it was. Plan A didn't work so it was on to Plan B, which did work for the defense. I don't know what juror #5 said to get kicked off, but Plan A sure makes me believe she was targetted and was removed over something trivial so that later the defense could not use it as an appeal.
I also believe that while it did make Jodi happy to have the juror kicked off it is not what made her so giddy that day. I believe that during the in chambers meeting alot of hurt was shown by the juror and Travis' sisters. I think she took alot of pleasure in thier pain. Inflicting pain on others is a joy to Jodi. She is pure evil. IMO
The defense might have a jury consultant watching the jury, although those people are expensive.
