Two words...COMMON SENSE.
Yup...common sense is what is on trial today, and that was exposed by the prosecution having to introduce "reasonable doubt" into the evidence that THEY presented into the case that THEY are prosecuting! It was eerily reminiscent of a "Three Stooges" episode where they were representatives of the law firm "Dewey, Cheatem and Howe".
The original investigating officers filed no charges, and did not arrest George Zimmerman because...regardless of what had happened UNTIL the shooting, the EVIDENCE at the scene of the shooting, combined with neighborhood 9-1-1 call recordings, George Zimmerman's call to the police non-emergency line and eyewitness accounts indicated that Zimmerman acted in self-defense against a younger, taller, more lithe and agile attacker.
Most people have already made up their minds about the guilt or innocence of George Zimmerman, and are already preparing their reaction to the verdict, whatever it may be. But the bottom line is...For most, COMMON SENSE has already been tried and executed.
