I really liked this book by NYPD detective Rick Cowan, about Operation Wasteland, the undercover investigation that crippled the garbage hauling rackets in NYC. I don't tend to be partial to books by police officers, maybe having been burned by the stunning dullness of [b:Donnie Brasco|308251|Donnie Brasco|Joseph D. Pistone|http://photo.goodreads.com/books/1173606424s/308251.jpg|299208] early on in my true-crime-reading career. But I found this much more interesting, maybe because Cowan was younger and greener and, at least as he portrays it, had to do more improvising due to the lesser resources of the NYPD vs. the FBI. There's also some great stuff about inter-departmental politics and lower-grade corruption in NYC; for instance, a leak about Operation Wasteland led to the city government opening up the hauling contracts for the NYC Marathon to an out-of-state company for the first time. Lots of great political gems like that, viewed from street level. I enjoyed this more than I expected to.
