ITA and yet she is arrogant enough to think she did a good job, so much so that she thinks her everchanging stories "I have no idea what happened", "A couple of strangers did it", and "Oh yes, it was self-defense" will work for her.
She's so delusionally cocky to proclaim -years later- "No jury will ever convict ME!" while trying to manufacture evidence against Travis (the "pedo letters") that despite doing an awful job of cleaning up the crime scene, she's cool as a (nasty) cucumber as she goes on trial for murder.
Unbelievable.
