well i still cant see pizzi partnering up with del balso to begin with, let alone with full knowledge that a man who once tried to murder him (rochebrun) was part of del balsos crew. second the last confirmed arson or any type of attack against pizzi/barberio dates to may 30. one week later del balso is murdered and not a single arson since. could be a coincidence or not.

the other theory could be that the arsons/attacks against pizzi/barberio have nothing to do with either leonardo or del balso and are part of an ongoing feud with another crime group.
