It makes zero sense for all of those bosses to take off running the way they did. What if they had stayed put? What could the police really do about a bunch of friends getting together at a backyard BBQ? It seems to me that the arrests and raid wouldn't have happened if not for them scurrying in all directions like cockroaches. I believe that Mafia history would have turned out differently if they had just carried on with their function and let the police watch, like who cares?
