Ok, sure, but that's not really a useful metric for a low population density area. Crime in my area is very low, violent crime especially, there's simply no need for that many police - they'd be doing nothing most of the time, if not for running speed traps and harassing bored teenagers.
The police force doesn’t need to be spread evenly, especially in areas with little crime.
A lot of rural towns are at least as dependent on highway patrol and sheriffs.
