Think about that statement for a second. How can that statement be true? For that statement to be true, it defies all the facts that we know so far.
How could Trayvon even see or feel a gun? It was dark and Zimmerman had on a large coat. The gun according to GZ was on his hip behind his back. They end up on the ground with Trayvon on top of GZ. So we have approximately 350 lbs laying on top of the gun. GZ has a broken nose, is having his head slammed into concrete, he has been over powered, mounted, and being beat about the head. But some how Trayvon sees, feels (no idea how this could even be possible), and goes for his gun.
Now with all this going on GZ is able reach down, unholster the gun and shoot his attacker. Only fingerprints on the gun belonged to GZ. Its just not possible.
Let me tell you what probably happened.
When John said he was going go call the cops, Trayvon heard that and was getting from off top of GZ, which allowed GZ to reach behind his back and pull the gun. GZ is holding onto to Trayvon's sweatshirt, Trayvon sees the gun and starts screaming. Out of anger GZ shoots him. There is just no other way to explain how GZ could unholster his weapon from under his coat, behind him on his hip, with a 160-170lb kid on top of him beating him, unless the kid stopped and was attempting to get off from being on top.
I would also be very interested in knowing the fingerprints that were lifted from the gun. Where they are on the weapon and from which hand the prints are from.
What you describe is also very clearly self defense.
Assailant on top, victim on back after being brutally and repeatedly beaten about face, head and skull.
Martin on top with Zimmerman on back is what makes it such clear self defense.
