Good to see SF cops have a fun side, putting a Beach Boys song to a simple ride down Lumbard street. I would love to see contour footage of a police chase down any SF street. In my experience SF cops seem to be the coolest laid back cops of any city I've been in, they let people enjoy themselves and don't get a power trip like cops in other cities, they actually go by the saying: "to serve and protect." They don't hassle people for BS reasons... in my experience anyway.
