Was he referring to American history (Guilani) or world history? Either case I would disagree to some extent.
Why use that comparison to black dealers?
@botz Yes, they still can fall under gang. There are many definitions of "gang" and just our society seem to conjure up images of bangers/bikers since they been called a gang left and right. But la cosa nostra is included as well since they're roots goes back to being one themselves. After all a "mob" is an organized "gang".
