And even with a manslaughter charge, I'd want to see a good explanation from the prosecution as to how the shooting took place in nearly the exact location where he was advised that they didn't need him to pursue, three minutes earlier.
I still do not understand how following someone on the public streets give the person being follow a license to attacked the follower or take away the follower right to defend himself from such an attack.
If Zimmerman had kept following Trayvon, we would have no evidence indicating which one of them initiated the assault.
However, with Zimmerman ending his pursuit three minutes earlier, that makes it look much more likely that Trayvon initiated the assault, since as far as I can see, the only way it could have happened is with Trayvon doubling back to confront Zimmerman.
However, maybe the prosecution can make a case that there is another reason the confrontation happened at that location. I'm willing to hear what they have to say.
But if they have no explanation for it (or their explanation is clearly bogus), that is going to be a pretty serious flaw in their case.
