PUBLIC ENEMY star PROFESSOR GRIFF has attacked the modern state of rap music, and accuses 50 CENT of teaching children to be violent. The 1980s hip-hop hero also attacks 50 Cent's movie GET RICH OR DIE TRYIN', which semi-autobiographically charts the CANDY SHOP star's rise to fame. He says, "Rap has become a sad reality. 50 Cent comes out with a movie that's a step-by-step instruction in how to be a thug. And sells it to children."
