Do this many people still have their panties in a bind over a case the jury clearly got right and which never had any evidence which merited it going to court? So what if Zimmerman is scum. It changes nothing.
Or it could be that some people think he murdered that kid even though the jury got it right due to the lack of evidence, and that those same people think he continues to be a danger to society and, for that reason, his subsequent behavior and arrest is newsworthy.
Actually, there was a ton of evidence. There was an eye-witness who saw Martin beating on Zimmerman. There is a 9-11 call that you can hear a man screaming, which is without a doubt Zimmerman. Unless you are stupid enough to want to believe that Martin while on top of Zimmerman beating on him 'MMA style' was the one screaming for his life. There is forensic evidence which supports Zimmerman shooting at close distance. There were injuries to Zimmerman documented by photos. There were grass stains on Zimmerman's back. Zimmerman was interrogated multiple times by authorities, and the lead investigator believed Zimmerman was basically telling the truth.
ETA: All the
experts and Martin fanatics told me there would be more evidence brought out in the trial which would prove Zimmerman's guilt. Time after time, what little new evidence was revealed exonerated Zimmerman even more. It was a horrible case, and the prosecution did the absolute best job they could of trying to focus on the emotional aspects of the case, but the facts certainly did not support a prima facie case against the defendant.
