Wow, you are brave, I have read (or skim read) every post in this thread. But I have done so as the thread evolved.
I see the main issue as this:
-the evidence has been dribbled and spun out, dribbled by the sources and then spun out by everyone else.
I was upset because a 17 yo engaged in daily activities is dead. ( I would be upset if it happened to any one, but I have a 17yo son, so that is a hook) When we go on trips we give our son considerable latitude to explore on his own, like in Newport OR, or Cape Perpetua OR.
Now especially if we were staying in Gainesville FL, where my father lives, I can see us letting him go to the store to get tea and a snack.
So I think it is going to come down to what happens, if you are following someone and a fight breaks out. Who has the culpability.
And this one will be a mess, we only have GZ's testimony. We have the testimony of TM's girlfriend. And then all the unknown forensics that will be revealed at the trial (if there is one).
Now I also have had personal experience in being followed and approached by strangers I find questionable. It usually involves me yelling "NO GET THE HELL AWAY FROM ME" in a very loud voice, getting safe and calling the police.
My own personal feeling is that GZ had every legal right to follow Trayvon, however I am not sure what the legal ramifications are of him approaching TM and questioning him. Especially since we will never know the actual details of that encounter. I do question how it happened that in the process of questioning someone else, a fight ensued.
I again would have been yelling my fool head off.
