Between burnout, and underpay, they lose the more intelligent ones quite quickly.
A few years back, I did some work for a UK police force, as a (sub)contractor. One of the other guys actually asked the Chief constable why they were using us, not doing it in-house. It turned out they tried. Every time they trained up officers to do it, they quickly jumped ship to the private sector.
Plus side, excessive machoism is discouraged too, so the police tend to be a lot more polite than American police. Effectiveness is another story.
