Black Gangster Disciple & Crips Gang


All five courses in the Gang & Inmate Secret Codes certification are designed to provide law enforcement officers, criminal justice students and workers, or anyone interested in the secret world of gang members and inmates with the knowledge of the covert methods of communication in correctional facilities and in other situations where secret communication is used. If you’re a fan of Dan Brown books, you’ll find Gary’s courses fascinating and a real eye opener into the clandestine world of gangs. The emphasis is on deciphering and code-cracking of real confiscated documents. The courses are designed using plain language, actual pictures and documents, exercises, and questions to test your understanding.
