As to the racist angle - of the other people that GZ called to inform the police about (and perhaps followed as well) during his time on neighborhood watch, how many were black? Also how many of those did he confront or question? If there were as many incidents as reported, I would think that is his MO to question everyone irregardless of race or age or gender he deemed suspicious rather than just this one black teen. And apparently he never had a physical altercation with any of those people either.
