I've read that article a long time ago. It says that they work TOGETHER. Ethnic groups aren't going to war like that in real life. I haven't seen a single case where Nigerians killed Camorra mobsters, but we do have the Castel Volturno massacre where the Camorra whacked a bunch of Nigerians. Until some news come out where Nigerians do the same to the Camorra I'm not believing that they're taking over. Also, Nigerians are being used as a scapegoat, like other migrants, for the real powers.
