Provides that school district may not prohibit active or retired law enforcement officer or registered security officer from carrying firearm in performance of school security duties if authorized under State law to carry.

This bill prohibits New Jersey school districts from banning active or retired law enforcement officers (including school resource officers) or registered security officers from carrying firearms while performing school security duties, provided those officers are already authorized to carry firearms under state law. It directly affects school districts that contract with such officers, requiring them to allow firearm carry during security duties if state law permits it. The key provision overrides existing restrictions (like N.J.S.2C:39-5) that might otherwise prevent officers from carrying weapons in schools. The law takes effect immediately upon passage.
