Quote from CaptainObvious:
Yes, the apparent lack of Martins blood on Zimmerman is problematic for him, IF the eyewitness accounts are true.
If you look closely you can see what appears to be an open wound on the back of Z's head, so it's highly unlikely would be able to create such an event such as slamming his own head into the concrete at such an angle.
There is still much forensic evidence which we have not seen. I still say that evidence will tell the tale.
I don't think that's much of an issue... People don't just gush out blood on being shot... Or maybe he did have Trayvon's blood on him and we don't know!?
I think it's more important to determine the angle and distance of the shooting.
Anyway, he now has some credibility to his self-defense theory.
