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

Is it also a realization at this point by the criminals that they are likely to not be put in a shoot or be shot situation? I mean at this point the cops will do what needs to be done through non violent means. Suspects I'm sure know this so are more willing to surrender as the fear of being shot and the escalating events leading up to it seemed to be toned down.

However or whatever it works, it is a good situation for other municipalities to look at and emulate.
