I think the phone call home from the inmate shows several things, but two of the most important are ICA is a bully and that she has no empathy or emotions herself except anger and contempt, manipulation and lies.
I think this phone call home will show the jurors that she is a psychopath.
All testimony from here on out will be colored by this ONE phone call where they get to hear ICA herself. This is what they will think about when they listen to the sheriffs deputies, detectives, SEARCHERS (think about how the jury is going to perceive that one), FBI Agents, friends and loved ones etc!
Then the forensic evidence will come in and JB, DS, and CM will attack them... and this especially will not go over well. These scientists don't have a vendetta out for Casey. These scientists have gone to numerous years of training and school they are conducting their lives, doing their jobs and trying to make a difference in the world! Casey was a liar, a leech, a mooch and a bully who didn't want to work and only wanted to party, play, shop, get her nails done and get more tattoos, have sex and go to clubs!
She is cooked... done... over!
I can't wait to watch it unfold and see our sweet baby Caylee receive justice, once and for all... she has been waiting for this for far too long and this has cost the taxpayers of Florida way too much money!
