But, they do conveniently tick the box of requiring a degree and do weed out anyone too who might question system too much or show too much empathy.

As someone who lives in a big city full of cops and who has to live next to a few people in law enforcement, it doesn't seem as though my city college or even my state university system degree programs keep ugly, nasty people from going into law enforcement. Family friend graduated with a law degree from Harvard and became a DA down in Austin, TX. It wasn't Harvard that cheese-grated away her soul. I'll spot you that plenty of local schools can be corrupted by the financial advantage of funneling people through a Cop School curriculum. But the thing that really seems to turn people into assholes and monsters is the job of being a cop.
