Mark Kleiman demonstrates that simply locking up more people for lengthier terms is no longer a workable crime-control strategy. But, says Kleiman, there has been a revolution--largely unnoticed by the press--in controlling crime by means other than brute-force incarceration: substituting swiftness and certainty of punishment for randomized severity, concentrating enforcement resources rather than dispersing them, communicating specific threats of punishment to specific offenders, and enforcing probation and parole conditions to make community corrections a genuine alternative to incarceration. As Kleiman shows, "zero tolerance" is nonsense: there are always more offenses than there is punishment capacity. But, it is possible--and essential--to create focused zero tolerance, by clearly specifying the rules and then delivering the promised sanctions every time the rules are broken.
Brute-force crime control has been a costly mistake, both socially and financially. Now that we know how to do better, it would be immoral not to put that knowledge to work.
