LCN members/associates, Sicilian Cosa Nostra, Naples Camorra, Russian groups, etc. Not only U.S gangs. Any crime groups that also gave youthful membership (20s per say).[/quote]

I'm not underestimating their influence but criminals regardless of which groups their membership/association they belong to aren't immune to internal vendetta due to personal disrespect or fallouts. Some of those cartels have splintered and usually not on good terms.
