43 Traitors: ..While successful in tracking down evidence of expenses, investigators encountered considerable difficulty in finding direct evidence of income. As Frank Wilson recalled years later, “I prowled the crummy streets of Cicero, where a twitch of Al’s little finger had the force of an edict, but there was no clue that a dollar from the big gambling places, the horse parlors, the brothels, or the bootleg joints ever reached his coffers." Potential witnesses, when subpoenaed, rarely cooperated. Wilson described most as either "hostile to government and ready to give perjured testimony" or "so full of fear of the Capone organization...that they evaded, lied, or left town."
