No Sidewalk! Life?

This image is a rejection of everything Jane Jacobs stood for when she advocated sidewalk life. A Chicago Tribune article (available although registration is required) covers the debate about sidewalks in suburbs. Here Hubert Frank is adamantly opposed to sidewalks, "Who knows what you'd be encouraging to come through" he wonders. While those following the spirit of Jane Jacobs might frame this question as an affirmation of all of the wonders and possibilities of urban social life, Mr. Frank worries that the carefully purified social space he inhabits will be polluted by a nameless, faceless other. How much paranoia must dominate one's mental life when something as mundane (in the best sense of this word) as a sidewalk is seen as an attraction or pathway for a dangerous other?
