Abuse: Failure of sex offender alert programs

NYTimes

In all 50 states, registries of sex offenders have grown sophisticated and accessible in recent years, a response to high-profile attacks on children. People can search their neighborhoods for former convicts on state-run Web sites, sign up for private services that alert them if an offender moves nearby, even download an iPhone application, "Offender Locator."

But the case of Phillip Garrido, the California man accused of kidnapping a young girl and holding her captive for 18 years, is reigniting a debate about the usefulness of the government-managed lists and whether they might create a false sense of public safety.

Mr. Garrido, who had been convicted of kidnapping and rape in the 1970s, was listed, as required, on California's sex-offender registry (complete with a description of the surgical scar on his abdomen and his 196-pound weight) and had dutifully checked in with the local authorities each year for the past decade — all while, officials say, his victim and the two children he is accused of fathering with her were living in his backyard.

Sex offender lists have made far more information readily available to the public and the police than before, but experts say little research is available to suggest that the registries have actually discouraged offenders from committing new crimes.

And some experts say that the lists may lead people to presume that anyone registered must also be elaborately monitored, when, in truth, monitoring ranges enormously from place to place and state to state. In some cases, it amounts to little more than an offender mailing a postcard with his address to a police department once a year.[...]
