New Jersey's attorney general issued new rules today on how police officers use force, specifically when dealing with situations involving barricaded subjects who are frequently in a behavioral or mental health crisis.

The new policy requires mental health professionals to join with officers during negotiations by offering guidance or by communicating with the person who's barricaded.

It also directs first responding officers to wait for appropriate resources to arrive and not force a resolution among several other items.

The attorney general's directives will take effect in October, and, according to the office, comes after more than a year of studies and meetings with law enforcement agencies across the country.
