man, tupac shakur has the song about -- it's called "your mama," and it's about his mom who was a brilliant political activist who for a while suffered from an addiction to drugs. his dad wasn't in the picture. and the dope boys on the corner who helped raise him. they helped make him a man. so does hip-hop consider current events? yes. does it kind of put that through a wash of art and culture and history? it absolutely does. >> host: paul butler, you write: i became a prosecutor because i hate bullies. i stopped being a prosecutor because i hate bullies. >> guest: so i grew up in chicago, and you can't as a young black kid in chicago have a view, an eyed listic, romantic view of the policing with your friends, as the guys who help you when your cat gets stuck in a tree. of that's not how it was where i grew up. and when i went to law school, people thought that i was this kind of down for the cause brother who would come out and work for legal aid or be a public defender. but i'd heard that prosecutors had all this power. and the way to make a change was to create change from the inside.
