4. Young Buck
This G-Unit rapper was just sentenced to 18 months in prison. Already a felon, he was caught with hip-hop's most obvious crime, hoarding firearms at his mansion. But how did Young Buck become a felon in the first place? Oh, that's right, he stabbed a guy at the 2004 VIBE Awards for stepping the wrong way to Dr. Dre. At least he's loyal.
3. Kareem "Biggs" Burke
This Roc-A-Fella co-founder was sentenced to five years in prison yesterday for his part in a giant marijuana distribution operation. He was caught on wiretap discussing details in a grow house, and being friends with Jay-Z can't save him now. He plead guilty to conspiring to distribute more than 100 kilos of the good stuff. But he probably should've just kept to pushing records.
