Naples, August 23 - A key ex-mafia witness of the Naples-based Camorra gave a television interview broadcast Thursday in which he said he regretted ever helping law enforcement. "If I could turn back, I wouldn't become an informant. The institutions have abandoned us. When they failed to slaughter me physically, they sought to destroy me economically and morally," Carmine Schiavone told Sky Tg 24. The former boss of the Casalesi clan began collaborating with the justice system in 1993, and served as the prosecution's chief witness in a major trial in which 16 senior Casalesi gang members were given life sentences. "I was one of the leaders. I really was sorry. My problem was precisely that I was truly remorseful, because in Italy there was no justice, law or politician who knows how to understand this," Schiavone added. "Who made me live in this world of mangy dogs? It is true that we fired shots, but the ministers, the paramilitary Carabinieri police, the magistrates, the regular police are more responsible than me because they permitted this". Speaking of toxic refuse buried in the coastline of the Domizia Bay north of Naples, the ex-informant said fighting the mafia was a losing battle. "The mafia will never be destroyed because there are too many economic and electoral interests", he said. "The mafia will never die".
