How About a Wi-Creep-edia?
A WiCreepedia would allow for tracking of anyone convicted of serious sexual acts. It could be abused to slander people and of course the predators themselves could quickly update their own info to cleanse or throw people off track. But at a minimum anyone who has abducted a stranger is almost certainly a continuing danger to society. There is no excusing an act like that - it is quite simply pathological, and its perpetrator almost certainly irredeemable. The existing list allows you to find a specific offender or find offenders within a specific jurisdiction. But we need one that allows searches by type of offense, age of victim, parole status, etc. If the citizenry could have such a tool, we might be able to flush out more of these unsolved atrocities.
