All police officers on patrol across New Jersey will be required to wear body cameras under new legislation signed by Gov. Phil Murphy on Tuesday.

The bill has been around since 2014 but passed the Legislature after this summer’s Black Lives Matter protests. New Jersey joins five other states requiring law enforcement to wear the cameras.

About 12,000 officers in the state already wear the cameras, but that’s just a third of the overall number of officers. The legislation requires the remaining departments to equip officers on patrol with the cameras.

Attorney General Gurbir Grewal says that the new legislation will improve the trust between the community and law enforcement.

"We take an important step towards the uniform, statewide deployment of body-worn cameras. And at the same time, we take yet another step toward ensuring…that New Jersey remains a national leader on policing policies and best practices,” Grewal said.

Lawmakers have introduced but not yet passed a funding measure for the cameras. The Department of Law and Public Safety estimates that outfitting police officers with nearly 26,000 cameras will cost just over $55 million.
