His findings are detailed in a thoroughly-researched work of non-fiction called The Street. See here for more.
"A day wouldn't go by, almost every few hours, where a police officer receives a bribe from a drug dealer. And it's right out in the open and once you've seen it you can't un-see it. It's so obvious," he says.
