Yes. When every little town has its own police force and everyone has to handle all their own administrative matters, hiring, training, etc you create a lot of inefficiency, variability in standards and performance and reduce the ability to do oversight.
In my opinion, policing has huge issues with not enough oversight, not wisely spent budgets, and not nearly enough training and qualifications as European countries for example. However, I think the biggest issue is that our Social system does not have nearly enough money and there's expectation for the police to handle everything
