Geography and Sex Offenders

1554 Walnut Avenue Antioch , antioch ca - Google Maps

Hindsight is 20 20 but wouldn't a simple Internet connection and Google Maps combined with the fact that the guy who kidnapped and imprisoned that poor California girl for 18 years was a registered sex offender have enabled the police or other authorities to rescue her sooner?  A Google mashup of locations of registered sex offenders combined with the link above would have shown something fishy going on.  Seems that local building or zoning code enforcement using the Google Maps tool would have revealed some serious code violations.  A GIS map of property lines and the image above would have shown that he was running some sort of illicit activity on part of his property.
