Background evidence:
I believe a deal has been worked out between the Martin family, the prosecutor and Z. Have you noticed that the mother has recently said, that what she really wanted was an arrest of Z... not that she was pushing for a guilty verdict regardless of guilt. They all know now what went down, and they all know the propensity of T pushing the envelope, testing out his growing taste for thuggish behavior in newly actualized adult, brutish body.
Z likely is remorseful, and wishes things had not gone down the way they did, but still, he is left with the proposition, that it was either himself or T that would die that night, and justifiable homicide is everybody's conclusion. T's family knows, they knew the path he was choosing, they knew if he didn't get back to the straight and narrow, he would either wind up dead or going to jail for killing someone, they knew.
No....they know the people who saw Tray beating the sh** out of Zimmerman....and she ain’t gonna lie for nobody.
SO.... if it had been a ‘black’ neighborhood watch captain, and a Hispanic ‘hoodlum’, would the ‘black’ guy have been arrested?
