One broken window, left unrepaired for any substantial length of time, instills in the inhabitants of the building a sense of abandonment - a sense that the powers that be don't care about the building. So another window gets broken. People start littering. Graffiti appears. Serious structural damage begins. In a relatively short space of time, the building becomes damaged beyond the owner's desire to fix it, and the sense of abandonment becomes reality.
