State prosecutors have been forced to drop dozens of cases against convicted sex offenders because of “loopholes” in Megan’s Law, according to the Pennsylvania District Attorneys Association, prompting it to call for immediate legislative action to fix what it sees as errors in the 16-year-old law.

Meanwhile, three state senators have introduced legislation proposing several changes to bring Megan’s Law into compliance with a federal statute, the Sex Offender Registration and Notification Act (SORNA).
