"nationwide, we call recruits that score to highly on intake tests.".

"Nationwide, cops outside the county or town they work in help them"

I can think of many communities where you have to have a four year criminal justice degree, and residency requirements to serve in their communities. The states where they don't have either of those things, is where you find more corrupt police. My state has a four year degree requirement, but not a residency requirement. Before they repealed The residency requirement, cops were actually quite decent.
