The Dai Li warriors seem to be an allusion to the secret police that are found in almost every totalitarian regime. Some examples are the Gestapo in Nazi Germany, and the Cheka and KGB of the USSR. These groups of secret police were in charge of "keeping order" by finding those not 100% for the cause of the nation. They did this through , spying, and threats. They would often kill, or dissapear, someone not doing something 100% correctly.
