Maybe you have seen this before, but somehow, this nugget slipped my attention until recently. During Jodi Arias' father's police interrogation, he not only spoke about a gun being stolen from Jodi's grandparents' home, but also indicated that Jodi Arias told him she had a gun and needed it for protection.
My guess is this statements was eliminated from the trial due to being too prejudicial, but I'm wondering how it missed my notice all this time!
According to her father's testimony, when he asked her why she had a gun, Jodi Arias replied, "Where I'm going I might need one."
You can hear the statement in the video below, by fast-forwarding to 11:00 in the tape.
