Roger served over 20 years with the NYPD, where he spearheaded the NYPD’s first dedicated facial recognition unit. The unit has conducted more than 8,500 facial recognition investigations, with over 3,000 possible matches and approximately 2,000 arrests. Roger’s enhancement techniques are now recognized worldwide and have changed law enforcement’s approach to the utilization of facial recognition technology.
Gang members use hand signs to communicate with each other and to challenge rival members or law enforcement officers in what they call "throwing signs." After forming in Los Angeles in the early 1970s, the Bloods street gang spread to the East Coast and formed "sets." These sets include the Piru Bloods, Fruit Town Brims, and South Side Brims (in western Maryland). The hand signs in this gallery were recovered during a multi-agency investigation earlier this year.
