All kidding aside. It was guys like caracappa and eppolito that helped give the mafia its strength. People were always afraid the cops were on the mobs payroll and if they ever complained about mob guys, the crooked cops would get wind of it. Thats why you have the witness protection. It was much harder for a crooked cop to determine the whereabouts of a cooperator.
Law enforcement should be held to much higher standards and caracappa and eppolito were certainly dealt with correctly. They are two evil people.
