Bikers and street gangs usually value one thing and that's with who they're going to make the most money. I can imagine the same goes for the Lebanese and whatever's left of the Irish in Montreal.
Hells Angels aren't going to go to war Desjardins just because he's French Canadian like most of them. They're not that clannish; at least not in the way the Sicilians or Calabrians are.

If the Sicilians decide to whack Desjardins, I doubt anyone will avenge him. It's all about the green.
