San Francisco is not happy about its sidewalks being stenciled to promote Justin Bieber's new "Purpose" album. City Attorney Dennis Herrera wants Bieber's label to cease and desist. "This prohibited marketing practice illegally exploits our City's walkable neighborhoods and robust tourism; intentionally creates visual distractions that pose risks to pedestrians on busy rights of way," he said in a note to Def Jam CEO Steve Bartels and Universal Music General Counsel and EVP Jeffrey Harleston.
