I am sure this has been asked and answered a million times (heck I've probably asked), does the jury know about all the above?
I do know that Juan asked Jodi on the stand about the 9mm she bought and Jodi said that she was going camping with a bunch of men and needed it for protection (buahaha, why go camping if you feel the need for a gun?) but as far as the knives, rental car and ammo, I don't think so. What a shame.
