Oh dude..... the letter proves that she set up the entire thing from the start. There's the seeds planted for the false abuse allegations, the convenient explanations for everything, the usual throwing blame on everyone (there's Jodi's trademark ), and then she swears she won't spend a day in jail for a heinous crime she didn't commit. Really, dude? Ms. Arias is beyond the pale. How disgusting of a person are you to kill a man then send his family a letter saying "Nah... I didn't do it, but these ninjas did. See what happened was your brother beat me, I never stalked him, I had premarital sex with him, he got me over at night for booty calls (tee hee), and we had to be secret because of his mean ex girlfriend. He even proposed, and he wouldn't let me move on. Now let me tell you how he died via ninja on his birthday. Rejoice in your joy and stuff!"
Nah. There's a special level of hell for this kind of depraved.
