Because the city is run by aliens?
What I heard the former mayor state is that several years ago, the city was having problems in the Hmong community with rival gangs, and they were set up to mediate those problems and bring the citizen's closer together. I see they have accomplished this. Right!!!! Once something like this is set up, they tend to stay part of the bureaucracy forever in spite of the fact that their stated mission is far from the activities they are engaged in.
