I should mention that it wasn't the only piece of evidence we looked over. We deliberated for around 6 hours I believe. Forgive me if I wasn't clear; I didn't intend to make it seem like I was the lone seeker of truth and made a grand argument to my peers; there was a lot discussed, by everybody. Also keep in mind that when you're on a jury, you only have so much to go on, and few resources with which to analyze. Thats why the phrasing is "beyond reasonable doubt."
