Black Rapper Down!

A week ago, rapper Shaquon Thomas posted a video making fun of a rival gang while pretending to hold a gun in his hands.

"You don't even know how to shoot," Thomas rapped in the video, titled "Shooters."

Early Friday, the 20-year-old Thomas was gunned down about a block from where he recorded that video on the streets of Uptown.  It's an area where three street gangs -- the Conservative Vice Lords, the Gangster Disciples and the Black P Stones -- have been locked in a long-running feud.  Thomas was a Gangster Disciple, according to police.
