When voters overwhelmingly approved Jessica's Law in fall 2006, many assumed it would lock away predatory child molesters and rapists who had slipped through the cracks of existing law.
But by key measures, Jessica's Law may be failing to deliver on its promise -- and in some respects producing the opposite of its intended effects.
As a Times investigation reported Sunday, the law has led far more sexual offenders to be evaluated and recommended for indefinite hospitalization after their prison terms end. But the number of commitments has barely budged.
In the 18 months after Jessica's Law took effect, only 42 of 67 defendants in civil commitment trials -- 63% -- were sent to hospitals, compared with 41 of 51 -- 80% -- before the law.
The finding is only the latest sign that the law, named for a 9-year-old rape and murder victim, is not working as intended, despite carrying costs that are expected to reach several hundred million dollars annually within a few years.
Critics have cited problems with another key provision that banned registered sex offenders from living within 2,000 feet of a school or park, in some cases ruling out entire cities.
The limits were meant to keep children safe. But the California Sex Offender Management Board suggested in a January oversight report that strict parolee residency requirements might tend to increase rather than reduce sex crimes. The panel said the number of offenders listing themselves as transient rose by 44% to nearly 2,900 in the first year after Jessica's Law passed.
"Current research concludes that suitable and stable housing for sex offenders is critical to reducing recidivism and increasing community safety," the panel said.
John La Fond, a retired law professor and author of "Preventing Sexual Violence," put it this way: "We're locking up a small number, then releasing the rest and saying 'Good luck, and you can't live anywhere.' "
State Sen. George Runner (R-Lancaster), who introduced Jessica's Law, said the concerns were strictly theoretical, unsupported by data showing an increase in sex crimes.
"We were prepared" for increased transience among sex offenders, he said. "That's why we require GPS."
He was referring to a provision of Jessica's Law that requires lifetime monitoring of many offenders using the global positioning system. But that part of the law has proved controversial as well, because local law enforcement agencies, which would eventually handle most of the monitoring, say they lack money for it.
