Usually when something is or is about to get heated, it gets shut down. I guess they didn't want another Zimmerman vs. Martin thread getting ugly. It's a touchy subject with both sides equally passionate about what they "think" happened. Fact is, we may never know for sure, but I can't wait to see/hear some more of the physical evidence in this case.
Here is one point that I haven't seen brought up by anyone. If Zimmerman didn't follow Trayvon, then T's body should have been right near Z's truck, right? Did he pull Z out of his truck? If Z listened to the dispatcher and went back to his truck, and then was "attacked" by T, wouldn't that place the crime scene right near the vehicle? I've been chewing on that one for a while now and would love to know the proximity of T's body (crime scene) to Z's vehicle. Makes you go hmmmmm
