You still work to deport or promote political movements, even in the town, to convince the haitians to self deport.

For example, a neighborhood watch could be set up to record illegal instances of conduct by the immigrants. As you mass report, you'll get more police involvement. Even if this force doesn't like it, you can use it to pressure state or county forces to get involved. Then you pay the police for overtime protective duty. Then the police are required to have a legal obligation to protect you (unlike normal). Since your paying the police more than the county, you subvert the government control. That's when you start running for judgeships and prosecutorships.
