The victim was Sparkle's niece.

Sparkle got on the stand and said it was her niece.

The victim didn't testify and that was enough to let him skate in the court.

"We" dropped the ball cause he basically got off on some bullshit, and the niggas that were gonna ride with him anyway used that as an excuse to keep supporting that fuck nigga. The rest used it as an excuse to make it OK to work with / make money with him again. Even though it's overwhelming evidence to the contrary. It snowballed from there.

Now that I think about it in retrospect, Piss on you may have helped his career because it was so popular. It added to the mythos.
