Having a front row seat to an era that becomes the stuff of legend for subsequent generations is a privilege. It’s even more of a privilege to have the talent to articulate what you saw and preserve it for posterity. Douglas Century is one of those lucky few. He got to witness a side of New York City that is now largely extinct. During the 1990’s, he hung out with surviving members of Brooklyn’s fabled Franklin Avenue Posse. He documented that experience into his first book “Street Kingdom: Five Years Inside the Franklin Avenue Posse.” It predated many of the true-crime novels that now populate “urban” book stores across America.
