The “Lagana's game is the only game in town. There is no recourse to his power, no court of appeal. There are no honest. cops, no Driscoll, no Crime Commission.

Those who resisted, the businessasusual organization men and the corrupt professionals, have been either converted or purged” (The Enemy Within 193-194).
