I have a long list of characters and social issues that are representative of the vibe of the western world at the moment, and I can’ pick them up and put them down as I need them.
As much as I love these shows, when it comes down to it, I feel bad about killing people (as a fiction writer). But kill (fictional) people I must.
Is the protagonist in law enforcement/legal fraternity, or an amateur? Are they established in the community or new to this place? Are they good at solving crimes or bad at it and manage to solve it in spite or themselves, or have a great sidekick?
