No registry required
Given technology has given people at their fingertips the ability to pull people’s information online, there really is no need for the registry. The registry was a tool in the age when paper and pencil was the way to track someone. Unless you are homeless, you are pretty sure to be listed somewhere online through some database via a utility bill, telephone number, voter registration, marriage, previous marriage, family, etc. So in reality, the registry needs to be done away with because LE can already get the info they want and need without someone having to come in to notify them.
Taking the registry back behind closed doors is unnecessary and a waste of time and money when there is the aforementioned ability currently in addition to the potential continuing ability to monitor someone who is no longer under the need to be monitored once their sentence is complete. Monitoring someone who has committed a sex offense and is out of incarceration is called parole, which already has a check in requirement. Once a sentence is done, it is done. If there is a need for monitoring outside of parole and a completed sentence, then it is a form of civil commitment without the barb wire, steel fences, concrete buildings and psych treatment because the person is still being monitored, every time they register, which still violates my Constitutional rights.
So, just doing away with a public registry is not enough, it needs to be done away with completely.
