[D]o registration and notification policies actually deter individuals inclined to commit sexual offenses and protect citizens?
A new study of ours shows that these policies are not effective in deterring crime or protecting citizens. We summarized 25 years of research and 474,640 formerly incarcerated sex offenders. We found that such policies do not reduce sexual or non-sexual recidivism.
If the policies are ineffective, then why do we have them?
These policies exist as a governmental response to community fear and outrage. There is political pressure to increase public safety. The problem is that these laws were enacted very quickly after child murder cases and became wide-reaching governmental mandates without research to back their existence and effectiveness. Fast forward 25 years, and the public and politicians are relying on window-dressing to feel safe.
