Clearly I've been defining it as removing problem areas within a city. The supreme court defined the entire issue as a non-federal issue and threw it back to the city governments to decide. If you have a problem with the decisions that your city government makes, try coming out for local elections (and I paint everyone with that brush, because the turnout is always pitifully low for these elections).
