Andrew Tangel and Mike Chalmers of The (Wilmington, Del.) News Journal found that sex offenders in the state of Delaware have been inadequately monitored. By mapping "the addresses of more than 1,200 moderate- and high-risk sex offenders, 1,900 child care centers and 350 public and private schools", Tangel and Chalmers found hundreds of instances where sex offencers were living within 500 feet of day cares - but day care centers don't count as schools under Delaware's lax version of Megan's law. They also found that 40% of sex offenders do not keep their addresses up-to-date in the system. Included in this report are details on how this investigation was done.
