Anthony,
I would point you to the list of online crime mapping websites, maintained by the MAPS (Mapping & Analysis for Public Safety) program at the National Institute of Justice. http://www.ojp.usdoj.gov/nij/maps/related.html to find some jurisdictions that have experience with developing online GIS applications, that depict location of registered sex offenders.
Particularly, take a look at the websites of the local jurisdictions in California. Many make the locations of sex offenders publicly available through interactive web-mapping applications. But, so does Tulsa, Oklahoma, Snohomish County, Washington, and I'm sure others out there.
Also, take a look at the MAPS publications, particularly "Crime Mapping and Data Confidentiality", which is free to download in PDF format.
You might find more information about privacy/confidentiality issues with GIS data, in the public health literature as they face the same issues as law enforcement does with protecting the privacy of offenders, crime victims, and sexual offenders, while balancing that with the public right to know.

List,
Has anyone had experience with developing a website or portal for public consumption/awareness that maps the locations of known and registered sexual offenders [or for that matter any other category of criminal activity that is in the digital public domain] ? In Florida at least, and I suspect the same may be the case in many other States, we have a state-level law enforcement agency that is mandated to record and register the "last known address" of individuals convicted of various sexual offenses. This website is, as you might imagine, non-spatial in its presentation, but contains the necessary spatial content to automatically and with regular frequency [because some of those individuals go back to jail and some new ones get out, almost on a daily basis], geocode and display on a map the locations of those "last known addresses", and perhaps, present the "attributes" of the individuals.
I'm more interested in the issues of policy, privacy and of course, legal considerations of such existing "location-based services" for this specific application. The technical is rather "mundane" and relatively straight-forward, however, the fact that the agency in charge of putting this information falls short of implementing tools that would map the individuals' locations indicates to me that perhaps some attorney somewhere was reluctant to provide the information in a geographic context. Quite understandable, given the potential powder-keg it could represent, but is it such and explosive issue or not? Looking for experiences in this or similarly, "edgy" public-domain issues.
Thanks, Anthony
