If you all noticed she immediately did the "If I was" to preface statements. anything she starts that way is "I DID IT". She's not that good of a liar as far as the context of her statements. She's a good liar as far as her eyes don't even expose her. I notice that on the stand, when she touches her face or covers her mouth - she's lying. Those are dead give aways for almost all people. She doesn't however do the eye's up or looking to the side (searching for information). To learn how deviant she is, look online for a tutorial in ready body languages.
I took this crazy course 2 summers ago in NY with an ex who's a magician. He's pretty stable in this field and booked everywhere. Why is he so good? Because he can read faces, eyes and body language. The man who held this course is an FBI consultant. It's amazing what you learn!
after I took the course I began looking at past documentaries of serial killers or mass murderers and watching their faces / bodies. Bundy, Ridgeway and a few others show no emotions when lying. That's (according to the course instructor) a psychopathic trait. Only a person that's a psychopath can pull that off. Again, it's not a diagnosis that Dr's like to give (it's seen as a sensational statement, the same with sociopaths). That's why you'll hear "She has psychopathic idealizations" or similar statements. It's so that she's not given a sensational title and the diagnosis isn't looked as being an attention grabber. Right now BPD is getting a lot of attention because most people are unaware of what that even means. Just like aspergers was given legs of it's own with Sandy Hook shooting. If she were a man - I wonder if she would have been given an aspergers title (avoidance, inability to know boundaries, incredibly detailed and obsessive). Women and men are always given different labels when it comes to actions like this.
There is a cathartic feeling for those who are true psychopaths who harbor anger from a deprived childhood, to act out in anger. It's absolute and controlled. People who have no control over their lives, they tend to find things they can control. For some it's food intake,sex or drugs. others it's violence on small children, animals or people who are rendered helpless. Jodi made TA helpless somehow and with that she made control over him. First she used sex (and the way she tells it, it was anal and oral copulation. IE pleasuring him and getting no pleasure but feeling PAIN (her way of feeling is through painful anal intercourse) She also knew that most women aren't giving those two things away out the gate. I'm guessing she did the anal for attention because it's "unusual" (and more so to a person who dates virgins) and for awhile it held him over. When that no longer worked, she had to do more and more.
Now, the issue with a murderer who has anger issues is that there are 3 stages: incubation, violence and relief. She would have absolutely reoffended at some point, because she knows there is relief for her after. This is why I don't think she HASNT done this before. If this was her first murder, there is definitely a dog or cat before him. I don't think it stopped with the dog she does admit to.
