I don't think she wanted to get caught; I think at the time she wasn't in the mindset to even consider consequences. Jodi was going to do what Jodi wanted to do, and that's all she was focused on on the way to Travis's. And yes, she IS really dumb, at least in the areas of common sense and reality! We WS'rs are always aware of just how (almost always) impossible it is to get away with murder, but many average people never ever consider what goes into a criminal investigation. Just look at all the idiots on shows like Oxygen's "Snapped", where killers stupidly never take into account things like cell phone pings, receipts, insurance policies and plain old human nature, meaning that people love to run their mouths. I used to teach high school, and sometimes a student would approach me to say "So-and-so is planning on skipping 7th period today..." And usually the "so-and-so" they were telling on was their close friend! I would be like, "Thanks for the info, but can you tell me why you told on your friend?" They'd say "I don't know"!! Point being, people can't keep secrets. Well Jodi didn't tell of any plans to kill TA but she was woefully ignorant about leaving hair/DNA/fingerprints at the crime scene- hello!! She apparently thought turning her phone off would cover her route, never considering how damning that action would be. She would have fared much better admitting she killed TA from the get-go, possibly getting 2nd degree conviction and a chance at regaining her life one day. Her ninja story is so absurd, and so cliche/movie-of-the-week; she had no idea how absurd it sounded. The narcissist in her felt she was perfectly believable. Jodi Arias is a scary, dangerous person. She tries to mask her emotions in court, but her anger/temper comes through anyway. Whenever she is really angry, her face turns a faint pink, spread across her nose and cheeks in a sunburn pattern. She is so deluded, and so grandiose in the way she sees herself. She is a good mimic/parrot when she needs to be seen as "sweet" or "positive," yet she just cannot 'get' how she appears to others.
