people should go easy on this girl. she knows she is stupid, which is why she didn't want no part of this trial. she knew she would be in over her head and that her lack of intelligance and ability to articulate herself would be exposed for the whole world to see. this is also why she is acting defiant at times.
the defense knows this too, and now they are trying to make use of the fact that she is stupid and make her contradict herself without looking like bullies and making the jury feel pitty for her. this is also why the judge is constantly intervening. so far i don't think the defense is particularly successful in what they are trying to do.
