most people are operating in a free market kind of environment, doesn't seem to many gangs around like the supreme team, pistol pete or any of those other crack era gangs. Theres been a steady decline in crack use and also the feds put the pressure on after pappy mason killed the cop in queens, theres probably only a few organisations that specialise in crack both at whole sale and street levels and make any real money off of it.

This guy just got convicted for running a cocaine operation supplying both powder and crack cocaine to various drug organisations in manhattan and the bronx.
