IMO, it just depends on how you look at it..The fact that Trayvon had no injuries only the small abrasion on his finger, tells me that Trayvon never laid a hand on GZ. GZ supposedly suffered a broken nose, two black eyes , head being bashed into the sidewalk but yet Trayvon avoided these attacks with his hands? The prosection emphasized this beating resulting from Trayvon using his "hands". IMO,, they know that to sustain those types of injuries that GZ had, using your hands, there would be evidence of that beating....Yet, Trayvon had none.
I think they would call on experts who could describe the type of bruising expected to show up on one's hands after breaking a nose, blacking two eyes, and banging someone's head onto cement.
JMO though
IF the "scuffle," the "wresting" and "fistfight" that have been reported, in the initial 911 calls and first interview statements, was actually TM "bashing GZ's head into the cement" and breaking GZ's nose, the
ME would expect to find evidence to support this BUT:
There was NO GZ DNA found on TM's hands, fingers or under his fingernails. There was no redness, swelling or bruising noted on TM's hands or knuckles. (GZ had his own blood on both the front of his face, back of his head and behind his ear lobes. Some of this should have transferred to TM's hands if he hand beaten GZ anywhere about the head or face.)
Just one small, 1/4" by 1/8" abrasion (tear) on TM's left ring finger in between a phalange and the top of his knuckles.
As to GZ, he had no contusions on the back of his head noted by LE who transported him, the Official LE photos (taken at the police station,) the EMT or the Family Medical Provider.
As to his nose:
The mark on the side of the bridge of his nose, slightly diagonal and vertical, with the small gauge of skin/scabbed appears to have been caused by something other than a fist or elbow.
Shoes: no information has been released, to date, which would give an indication as to whether there was GZ's DNA on the toe or heal of TM's shoes.
Knees of TM's Tan colored pants: No info as to whether there was GZ DNA of any kind, on TM's pants front or back.
Flashlight: No info has been released as to any DNA found on that item.
The Gun: No TM DNA or fingerprints were found on the handle of the gun and that was the only part that tested positive for the presence of possible blood.
Possibilities, based on the witness accounts, to explain the injuries to both TM and GZ and the lack of evidence or injuries on the same:
Bushes (No evidence reported from the bushes near the two scenes/"T" of sidewalks or where TM lay dead
Flashlight (no forensics released)
Gun
TM knee (no forensics released)
TM elbow (no forensics released)
TM foot (no forensics released)
It is curious that GZ does have a small knick on the outside of his right pinky finger between the top phalanges and the middle phalanges. TM's was on the left hand. If two people are face to face in a struggle the two injuries would be on the same side.
