ATLANTA (AP) — Atlanta’s mayor is vowing to change police use-of-force policies and require that officers receive continuous training in how to deescalate situations before the consequences become fatal.

Mayor Keisha Lance Bottoms announced her plans after the police killing of another black man, Rayshard Brooks, outside a fast-food restaurant on Friday touched off more large protests in the city.

“It’s very clear that our police officers are to be guardians and not warriors within our communities,” the mayor said.

Floyd’s death on May 25 after a white Minneapolis officer pressed his knee into the black man’s neck touched off demonstrations and scattered violence across the U.S., and Brooks’ killing rekindled those protests in Atlanta.

In Chicago, Mayor Lori Lightfoot said a panel of residents, activists and one police official will review the Police Department’s policy on when officers can use force.
