What led to this?

This is what happens to your country when you don't really care about public services (in many cases they're looked down upon, just look at teachers, federal workers but also police). There's difficulty recruiting and retaining police officers in the US (i'd imagine anywhere but especially the US) because it's not seen as a good job. I'm not a huge believer in IQ but intelligent and capable people just can't be convinced to go into this line of work unless they truly care about their community (very rare). Just way more fun to go to the big city and work in an office with an AC.

I'm sure there's a million other reasons why people don't want this job, but this reflects in how harsh you can be on (new) agents.
