Most of those who are trying to understand the #WEscandal and multiple other @JustinTrudeau scandals are attempting to do so in the context of the law and government. A more functional form of analysis would be to use criminal network analysis.
The most important players in a crime network are not the bosses/kingpins. The critical nodes are those built around the BROKERS who can connect all the relevant players. (Think Chief of Staff, certain Cab Mins). Brokers are all important players in a crime network.
