Edwards's article about Iavarone's murder is interesting because the story mentioned that people behind the murder weren't made, thus making them vulnerable to attack by the opposing group that consists of made members. If the article is correct, then we can rule out the Musitano group and Luppino-Violi group being on the outs. If it's not correct, I would stick to what I believe, which is that the Musitano group and the Luppino-Violi group are still on good terms after many years (this was definitely not the case in the 1990s).
