New Jersey Attorney General Gurbir Grewal has issued a handful of new directives to law enforcement, aimed at overhauling policing in the state.

Grewal says that the new directives will seek to improve how police and prosecutors handle investigations, including the release of video from incidents involving officers.

Grewal unveiled the directives Wednesday in Newark alongside State Police Superintendent Col. Patrick Callahan, other law enforcement officers and prosecutors.

"Our state faces a number of challenges but I'm confident that we can overcome them together, united in the goal of promoting public safety and public trust,” Grewal says.

Among the changes are a presumption in favor of publicly releasing any video recordings that show serious use of force by authorities.

Six cities in the state are helping to test a new use of force portal.
