The reason Jodi's family isn't testifying on her behalf is ~ JODI won't allow it. She's the one that made that decision.
The fact remains that throughout the entire trial, Jodi & her council painted Jodi's family as abusive to her. They've maintained for 4 months now that her family is nothing but a bunch of meanies, and that's why they can't put a single one of them on the stand to act like they now like her. Now, none if it's true, mind you... But, if they get up there now, it's going to be obvious that they DO in fact care about her, and Jodi will sit there seething and shooting them dirty looks ~ and none of it will sit well with that whole "my family's so mean to me" scenario. It'll just pull the lid off THAT particular lie, so what's the point?
This whole thing is such a farce...
