Six guys I grew up with were on the NYPD. None of them cared about any case 1/10 as much as depicted on this show.
Oh, I am sure. I often roll my eyes at how personally involved they get in the cases. One would just not have the time, for one thing. And for another, it would just be too draining emotionally.
Also, the brother cop and sister prosecutor would not be allowed to talk together about any of their work, much less work together the way they have so often.
Oh, well, it’s TV.
