My opinion does not matter at all first off, but I do feel like posting. I finally listened to the 911 tape of the shooting. Right from when I heard it, it sounded like a teenage boy yelling. They sounded like the yells I've heard from teenage boys where I work when one of them is angry or scared. I listened several times....I can't hear this being an adult man....and where I work I've heard a lot A LOT of adult men yelling. Of course I'm not the FBI or anyone else, just my opinion. I think that the independent tests got it right, but of course FBI will be the final opinion. I will say that even then, if they agree, there will be those who still wouldn't believe it. Regardless, it was very heart-wrenching to hear that and to hear Z's 911 calls. The hair went up on the back of my neck on Z's calls for the reason that here was someone documenting the last moments of someone's life; that someone not knowing that things were going to go south and that they would die. Very un-real feeling.
