The prosecution, in an effort to persuade the jury to disregard the prosecution's need to prove their case beyond a reasonable doubt, argued in its closing rebuttal for jury nullification of the law that requires that the jury find guilt beyond a reasonable doubt.
In judging Zimmerman's guilt, prosecutor John Guy told the jurors, "Should we not look into the heart of that grown man and the heart of that child?" "The human heart," prosecutor Guy argued, "moves us … motivates us."
The rebuttal even included a racial appeal (as John Adams did in defending the soldiers the Boston Massacre case). Guy argued: “This case is not about race” – despite the fact that the defense never said that it was. And then Guy made an argument that made it about race, switching the race of the defendant and Martin.
