Authorizes State, county, and municipal law enforcement officers to access certain crime scenes and evidence.

This bill authorizes all New Jersey state, county, and municipal law enforcement officers to access crime scenes and evidence under their agency's jurisdiction. It prohibits anyone - including federal officers - from blocking officers from these locations, treating such obstruction as a disorderly persons offense punishable by up to six months in jail or a $1,000 fine. The law requires the Attorney General to issue implementation guidelines and takes effect four months after enactment. It directly affects law enforcement access to evidence during investigations.
