Chicago is among the most respected members on this board. If anything, he has proven himself and you just fanboying the grand ave crew.
I think ChiTown accused him of being a fanboy of Elmwood Park. Which is strange considering Chicago has been saying Elmwood Park retreated a long time ago.
Bottom line, until further info comes forth, all we have is a few pieces of the puzzle given by comments of FBI officials in recent years. But what Chicago describes seems to match up with those comments - the Outfit being down to two or three crews, run in northern and southern sections, etc.
