After a study finds disturbing numbers of sex offenders taking up residency in the Bronx, a plan has been announced to keep local children at a safe distance.A new $100 million plan seeks to keep offenders away from schools.The money would fund GPS tracking for offenders living within two blocks of schools, expand online search capabilities for parents and community members and enforce stricter penalties for sex offenders who do not register their residency.Congressman Anthony Weiner?s office (D-NY) says studies show high-risk sex offenders must be thoroughly monitored. It says more than half of all sex offenders are likely to commit another sex crime within 25 years of their release.
