They caught some kid smoking grass 'judge threw the book' means harsh sentence. Opportunism in his eyes is ratting other people out for a reduced sentence. He's telling him to take his advice, they've got guys in and out of jail that will sneak up on them so stay on their good side. He tells him if he takes his sentence they've got friends that will keep him from getting raped or killed. Then he says if he pisses off the boys from Alabama they'll take him out.
