Every time I watch through Brooklyn Nine-Nine as background noise I find the show's assertion that the problems with police are not systemic but merely the rare bad apple one increment more distasteful.

B99: [solid episodes about race and sexuality]

Also B99: Planting EVIDENCE? Who DO that? POLICE never do that! Johnny Badcop you're a ROGUE and you are FIRED. Now the police are stainless again—please don't dwell on this too much ha ha look Boyle is trapped in the snack machine

We can only hope season eight chronicles Jake's cognitive dissonance as he grapples with the realization of what modern police are and do and that perhaps "I like Die Hard" was not a healthy reason to become a cop.

Boyle admits he came to this conclusion in season 2 but didn't want to disappoint him.
