In this episode, retired agent Mark Horton reviews Operation Impunity, an undercover investigation that targeted the New Breed Black Gangsters. The street gang was based in “The Square,” a Chicago housing complex plagued with gang violence and an open-air drug market. The faction of the Breeds operated with Impunity, committing murders and selling drugs with no fear of law enforcement.
In 2004, the Chicago Police Department (CPD) area 4 Gang Squad and the FBI Joint Task Force on Gangs (JTFG) began developing a strategy to dismantle the gang. The CPD would conduct street corner conspiracy and the FBI JTFG would begin working toward a Title III and a Group I UCO.
Mark Horton, initially the case agent, took on the undercover role, infiltrating the New Breed Black Gangsters as a business associate purchasing drugs from the gang.
“ Like they say, don’t become a monster when you’re chasing monsters. It was probably a little
bit over two years that I was hanging out with these guys. In order to fit in, you lose a little bit of who you truly are. It’s not normal for me to be talking about murders, to be abusing people, and selling drugs for the majority of my day.”—Retired Agent Mark Horton
