Maybe he had his fists clenched in a ball, maybe his fingernails never hit anything because of that and maybe this and that. ?
it would be prohibitive to slam someones head repeatedly into concrete with a clinched fist or by never touching his head, this and that - TM's DNA not on the weapon .... Zimmerman is lying
That is your take on the circumstantial evidence.
But we have direct evidence that Martin was on top of Zimmerman pounding him.
So what is your take on how he got a broken nose, abrasions on the back of his head and how Zimmerman's blood got on Martin's clothing?
What is your take on DIRECT EVIDENCE EYE WITNESS TESTIMONY?
Is that guy lying also?
Is the DNA expert that found Zimmerman's blood on Martin's clothing lying?
Is he lying when he stated that Martin was on top of Zimmerman when Zimmerman shot him?
What specifically is Zimmerman lying about?
