"Jessica’s Law too vague to enforce?"

The article is in today's San Diego Union-Tribune. The lead:

More than 70 percent of registered sex offenders in San Diego County are violating a state law by living too close to schools and parks.

Jessica’s Law, which was approved by California voters in November 2006, toughened sanctions against sex offenders and bars them from living within 2,000 feet of a school or park. In San Diego County, 1,266 of 1,731 offenders whose addresses are made public by the state live in those restricted zones, according to an analysis by the Watchdog Institute, a nonprofit investigative journalism unit based at San Diego State University.

That finding surprises virtually no one in law enforcement. They say the law is vague and has holes, making it nearly impossible to enforce.

For example, the law doesn’t specify whether residence restrictions apply to all convicted sex offenders or only to those who were convicted or paroled after it passed. There are no penalties for violating the restrictions.
