The love that San Francisco Justin Bieber fans have for the “Sorry” singer is forcing authorities to take legal action. Following Bieber’s graffiti promotion for his latest album, Purpose, fans have taken in his footsteps to paint the city streets green, blue, red, and plenty other colors. City Attorney Dennis Herrera says the actions of fans “illegally exploits our city’s walkable neighborhoods and robust tourism.” Someone will pay, and Herrera is looking at Bieber’s label to make those payments.
