IThe point that matters is by all physical evidence (broken nose, blood on back of head, etc.) that Travan attacked Zimmerman and Zimmerman was in fear of his life.
there is ZERO physical evidence of any of that.
notice on the surveillance video when the cops search zimmerman and touch his clothes? they wear gloves if there is blood around to avoid blood borne pathogens. FACT.
the fact that they did not wear gloves means no blood, even if they did take his clothes.
there is also zero evidence that martin attacked zimmerman, and given the long history of violence, aggression, and "snapping" that zimmerman has, it is more likely to conclude that zimmerman did the attacking and martin stood his ground.
how long does it take you to cover 200 yards?
