We went through some of the possibilities on another thread. My favorite was that there was an out-of-country mitigation witness (not subject to the court's jurisdiction or even to the jurisdiction of a court who could order a telephonic appearance from somewhere else in the US), who agreed to testify by phone/Skype but only if [list of demands].
Yes, I read those but the media have been reporting that it was JA as fact, corroborated by 3 witnesses, and Tweeterland have seemed to accept it as well. Also my theory that such a bold and narcissistic demand as bending the constitution fits so well with JA's personality. I know there's a theory that she could have been seen on the stand but was just laying foundation for the actual mystery witness. Could be, I guess.
