What does the white clown represent in Fahrenheit 451?

According to Wikipedia: "The whiteface character-type is often serious, all-knowing (even if not particularly smart), bossy and cocky. He is the ultimate authority figure. He serves the role of "straight-man" and sets up situations that can be turned funny."

This could symbolize the authority of the government. Although they are not "smart" they do assume authority and determine how others behave. The White Clown is also violent, which could mean that this society sees violence as a form of entertainment.
