again...I just cannot imagine anybody harassing you about photographing anything in San Francisco....watch for cars, bikes and dog poo...for sure.
Alas, Harvey Milk, you are missed. Dog poo was the issue that got him elected! Now that he's been dead I guess the city has lapsed in its vigilance. Then again, it's nowhere near as bad as it is in Buenos Aires, which has more dog poop on the sidewalks than the Korean DMZ has landmines.
