Not to support or rebuff the parent comment, but cultural homogeneity has everything to do with policing standards.

On the positive side, when people feel more connected to each other, more predictable, the odds for miscommunication or misinterpretation are greatly reduced. Further, people within such environments typically have stronger support systems.

On the negative side, there tends to be more pressure, from more sources, to do as those around you are doing. This is a double edged sword, as it can propagate both good and bad behaviors.

This all would play a role in defining police procedures, as it would contribute to a set of expectations, of the police and the people they are dealing with.
