From San Francisco Chronicle:
The San Francisco Board of Supervisors on Tuesday unanimously voted to outlaw the sale and possession of “ghost gun†kits and parts in the city, marking a key moment in what is emerging as a statewide battle against the untraceable weapons.
The ordinance allows police and the city attorney’s office to go after manufacturers and providers who profit off the sale of ghost gun kits and parts. Officials would be able to build up trafficking cases against them. Each violation or sale of a part would be punishable by a $1,000 fine.
