His Twitter avatar photo looks older than 14.
There's an old scar or something below his right eye, which is useful for sorting the fakes from the real.
His online presence is of somebody spoiling for a confrontation. His anger at being profiled by Zimmerman is fully justified. However, his assault on Zimmerman was a crime, and Zimmerman's response thereto was justifiable homicide. It's very unfortunate. If it hadn't happened, maybe he'd have become a great airplane mechanic. Or maybe not.
The opinion of the People of Florida does not matter and is worthy only of contempt. The white Corey is even uglier than the black one, BTW.
