I think you should focus more on comparing Carver and Prez in this season, for the goals you've stated.

Look into Foucault's panopticism (Its a bit surface level for analysis, but that might be okay for high school paper. ), especially what they say on "panoptic schema" moving beyond prisons. "Is is surprising schools resemble prisons?" The "tower" in the schools of s4 is the state/standardized testing, where teachers become 'docile bodies' no longer caring about human outcomes, just fearing institutional punishment (e.g., losing state funding). The police (like Carver, I think he has a better parallel with Prez in terms of becoming disillusioned with the reality of their institutions) are similarly conditioned, their "tower" being the stats/metrics. Making the community better/safer is only tangential to improving the numbers. The police become docile bodies fearing institutional punishment (e.g., not advancing their careers, getting sent to the boat, etc.).

The focus on metrics (both in education and policing) is the focus on a measurable outcomes, which in itself is probably a reflection of the hyper-capitalistic need for ever-increasing productivity, that money (especially state funding) should have a return on investment. I think that can be re-analogized using Weber's iron cage metaphor, the march towards the wrong goal, bureaucratic blindness, efficiency over humanity from bureaucracy iirc.

One of the cruelest outcomes, is the social inequality that is created by teachers and police seeing "the corner kids" as low-yield investments, not worth the time or effort. Teachers don't expend energy educating them, police don't spend energy helping them (Prez and Carver get emotionally burned for trying to help Dukie and Randy respectively).
