I think he is referring to Trayvon pounding Zimmerman's head against the sidewalk.
I believe Reasoning Logic is suggesting that if Trayvon had seen that Zimmerman was wearing a "neighborhood watch uniform", then Trayvon would not have engaged in violence against Zimmerman (and therefore would not have been shot in turn).

Do you have any evidence that Zimmerman challenged Trayvon?
