This practice has ruined an area and school in my hometown. This is an affluent and mostly white town. Thanks to Habitat and the county we have seen crime skyrocket. Many Katrina refuse.
The county used it as revenge for various parts of the county voting for cityhood and escaping their tax heavy service non-existant clutches.
We are having the same problem where I live. Lots of so called “katrina victims” coming back and are moving into my town. I'm not far from New Orleans. The best thing we got is the police take absolutely no crap from these people. It doesn't take long before they settle down and keep to themselves. I'm sure the NAACP will show up one day and claim the police are harassing them because their black.
