Increases penalty for harboring or concealing certain sex offenders.

This bill increases penalties for knowingly harboring or concealing a sex offender who has not complied with registration requirements under Megan's Law. It directly affects individuals who provide shelter or assistance to unregistered sex offenders, such as family members or others who are aware of the offender's non-compliance. The key provision mandates a minimum prison term without parole eligibility: 3 years for a third-degree offense (typically involving more serious underlying crimes) or 1 year for a fourth-degree offense. This change applies specifically to cases where the harboring involves sex offenders subject to Megan's Law registration, not general hindrance of law enforcement.
