But it is my belief that a solution to this problem is attainable. The solution may sound strange, even crazy. New ideas often sound that way. Here is my proposal. Criminals and law-abiding city dwellers must switch places-literally. Criminals should be released from prison. They will live in the perilous freedom of our cities. They will become victims of their own robberies, muggings, and killings. Eventually self-destruction will result.
