The news just said it was the white kids friend. That just leaves too many questions....
“The attack was videotaped by a youth from the neighborhood who uses a camera to capture images of skateboarding, said Damin, who refused to identify the boy. He said the youth gave his family a copy of what he recorded; they, in turn, released it to news outlets.”
“WVEC reported that the youth with the camera had been threatened at school for taping the assault.”

The news just said it was the white kid's friend.
The difference between friend and enemy is...... the friend posts it on YouTube.
