One of the most painful aspects of the George Zimmerman verdict is not that he was found not guilty, but that the verdict was so unsurprising. The message this verdict sent, that killing an unarmed African-American man for no particular or rational reason, is not a crime, is not new. On the contrary, it is a message that the criminal justice system has sent over and over again through the years, and only occasionally in the context of high-profile trials like that of George Zimmerman. Zimmerman's acquittal is a reminder that regardless of what our constitution or laws say, or of the ethnic background of the occupant of the White House, our criminal justice still does not treat all people as equal.
