It looks like this feud for now is starting to tip in favor of the Rizzuto clan. The Scoppa clan arrests are probably having an impact.
I think this is confusing. As Hollander stated, he was allegedly backing Giordano. In turn, it's unclear where Giordano stood in regard to Sollecito. This hit might have come from either of the warring factions. And how sure are we that it's Scoppa vs. Sollecito/Rizzuto?
