1. The Legislature finds and declares:
a. The danger of recidivism posed by sex offenders and offenders who commit other predatory acts against children, and the dangers posed by persons who prey on others as a result of mental illness, require a system of registration that will permit law enforcement officials to identify and alert the public when necessary for the public safety.
b. A system of registration of sex offenders and offenders who commit other predatory acts against children will provide law enforcement with additional information critical to preventing and promptly resolving incidents involving sexual abuse and missing persons.
