The critics note, for example, that the white youth who beat the black student at the party was charged only with simple battery, while the white man who pulled the shotgun at the convenience store wasn't charged with any crime at all. But the three black youths in that incident were arrested and accused of aggravated battery and theft after they wrestled the weapon from the man - in self-defense, they said.
Because it describes all of the incidents from the perspective of the unidentified "critics" without providing the opposite perspective. That is pretty obvious. I just don't think you are very good at this.
