I say we pull out police protection, they don't want police there, police don't want to patrol it, etc.
Lets kill two [or five] birds while we're at it; small town donations to "foster" a family who wants out of these ghettos. I'm sure my town could collect up enough in donations to buy a small house for a family who doesn't want their children getting sucked into gangs and thug culture, getting addicted to drugs and shit, parent(s) who wants their kids to go to a decent school. Move those that want to leave to smaller towns, have some local sponsors to help these folks adjust to the lifestyle outside failed cities. I think it'd help on so many different levels regarding issues we're having in big cities today.
