I prefer a book written by an educated or otherwise well read police officer who worked in a police unit which focused on gang activity.
My request is hyper-specific, so I'll offer a broader request.
I'm looking for books about gang activity written by someone who interacted with gangs rather than books written by researchers or observers. By "interacted with gangs" I mean members (especially leaders), those that did business with them, and those that investigated them (especially those that did so in a participatory style).
My hopes are to learn more about how gangs interact with each other. Justice porn is also appreciated. Thanks.
