Window-breaking does not necessarily occur on a large scale because some areas are inhabited by determined window-breakers whereas others are populated by window-lovers; rather, one unrepaired broken window is a signal that no one cares, and so breaking more windows costs nothing.

During the 1960s, one neighborhood in San Francisco had the lowest income, the highest unemployment rate, the highest proportion of families with incomes under four thousand dollars a year, the least educational attainment, the highest tuberculosis rate, and the highest proportion of substandard housing ... That neighborhood was called Chinatown. Yet, in 1965, there were only five persons of Chinese ancestry committed to prison in the entire state of California.

The view that we know less than we thought we knew about how to change the human condition came, in time, to be called neoconservatism. Many ... , myself included, disliked the term because we did not think we were conservative, neo or paleo. (I voted for John Kennedy, Lyndon Johnson and Hubert Humphrey and worked in the latter's presidential campaign.) It would have been better if we had been called policy skeptics; that is, people who thought it was hard, though not impossible, to make useful and important changes in public policy.

Many Americans have lost confidence in the way our criminal courts assess guilt and innocence. Whatever one thinks of the verdicts, the recent trials of O.J. Simpson, Erik and Lyle Menendez, and various defendants in preschool molestation cases have been lengthy, lawyer-dominated soap operas in which the search for truth has been subordinated to the manipulation of procedures.

What most needs explanation is not why some people are criminals, but why most people are not.
