A smooth sidewalk isn't going to make a cut less than a half inch long.
I don't see any great danger in the wounds he sustained, not enough to warrant homicide.
And if you are going to commit homicide, you need to be arrested.
The wounds would be just a part of the picture used by the defense lawyers.
They don't have to be severe for one to feel threatened.
Unless one wants to claim Zimmerman broke his own nose and scraped the back of his head then clearly there was an altercation which Martin seemed to have the best of.
Whether that was life threatening or not is easy to speculate on.
Things that will come out under oath in trial will sort this out. Such as.....
Cornoner states no wounds on Martin which will be verified with photos
Proximity of the gun to Martin when he was shot
Wounds or lack of found on Martin (excluding the gun shot obviously)
Martins blood or lack of on Zimmerman
Zimmerman's testimony as to the route he and Martin took leading to their confrontation
Zimmerman's testimony as to comments he and Martin made when they confronted each other
Police testimony as to the routes they believe Zimmerman and Martin took
Testimony from witnesses to what was seen and heard
Until there is some swearing on a bible it is all sheer speculation
Except for those who want a conviction regardless.
and John can stick his claims of racism where the sun don't shine. It has nothing to do with race and never did except for those who want it painted that way.
