Police in Berkeley, California, are now allowed to use pepper spray on violent protesters.
According to local media, Berkeley's city council voted 6-3 on Tuesday to change a two-decade-old policy that barred officers from using pepper spray for crowd control purposes.
Berkeley police have been allowed to carry small pepper spray cans for use on individual suspects during that time.
The revised policy authorizes police to discharge the weapon on people "who are committing acts of violence upon police or others."
But officers can't use pepper spray to control crowds, and they can't spray people participating in nonviolent protests, even if those protests are illegal.
The change comes after recent violent protests in the city. The police chief argued his officers need to be able to use pepper spray when protests get out of hand.
The council's decision comes ahead of planned speeches by several controversial figures at the University of California, Berkeley.
Those speakers include former Breitbart editor Ben Shapiro, former White House chief strategist Steve Bannon and conservative pundit Milo Yiannopoulos.
