A lot of good points have been made regarding my list and now I feel the need to give my reasons..
1. Charles "Lucky" Luciano (N.Y./N.J.) - Set up The Comission and orchestrated the hits on Joe Masseria and Sal Maranzano..
2. Carlo Gambino (N.Y./N.J.) - Led the Gambino family through a period of unprecedented prosperity.
3. Al Capone (Chi.)- Orchestrated St. Valentines Day Massacre..oh yeah and he's AL CAPONE!
4. Sam Giancana (Chi.) - May have had a hand in J.F.K assasination, and led Chi. Mob through some dangerous times.
5. Albert Anastasia (N.Y./N.J.) - Had a key hand in forming Murder Inc.
6. John Gotti (N.Y./N.J.) - Teflon Don, as mentioned Balls for days....
7. Vito Genovese (N.Y./N.J.) - Well known for ruthless nature..
8. Santo Traficante (FLA.) - May have had a hand in the Kennedy assasination.
9. Carlos Marcello (N.O.) - May have had a hand in the Kennedy assasination.
10. Nicodemo Scarfo (Phi.) - Well known for ruthless nature...
And this list is by no means a hard and fast ranking of who the all time best were..
