The Richmond, CA model of policing (positive community policing)

This sounds like a program that can succeed on a local level, but should not be implemented state or nation-wide. (That is, could be implemented state or nation-wide, but by individual communities so the program can be tailored to better suit them)

I agree. Policing needs to be administered at the state and local level, and a program like this could only work at that level. But, what do you take from this approach? Do you think it is attainable at a level of, say Baltimore or Los Angeles? I mean logistically, as well as philosophically speaking.
