...that Megan’s law has had no demonstrated effect on sexual offenses in New Jersey, calling into question the justification for start-up and operational costs. Megan’s Law has had no effect on time to first rearrest for known sex offenders and has not reduced sexual reoffending. Neither has it had an impact on the type of sexual reoffense or first-time sexual offense....Sentences received prior to the implementation of Megan’s Law were nearly twice as long as those received after the law’s passage, but time served has been approximately the same before and after the law’s enactment.
Author's Note: Many of the ideas I have formed about safety came from reading Gavin de Becker's book The Gift of Fear. I highly recommend this book for anyone interested in personal safety issues.
