TRENTON, N.J. — New Jersey's pioneering Megan's Law, which costs millions of dollars to alert citizens when sex offenders move nearby, may not make children safer, new research suggests.
A federally funded study under way in Trenton is trying to determine whether Megan's Law is worth the cost of its "enormously expensive" monitoring and enforcement requirements, said Phillip Witt, a consultant on the study.
A declining trend of sex attacks on children began before the law took effect and has continued, raising the suggestion that New Jersey's Megan's Law -- one of the first laws of its kind in the nation -- may not have influenced the trend, researchers say.
"We don't know whether Megan's Law really works," said Witt, who helped create the risk-assessment system used by New Jersey's courts to classify sex offenders.
"Just a few studies have looked at whether community notification laws are effective," he said. "I believe they have very little effect." ..Source.. by Sam Wood, The Philadelphia Inquirer
