Tough to do a show on that considering the time span involved but it would be interesting if they ever covered an episode where that happened.

Of course the show is not a broad coverage of the detectives process. The detectives featured almost always are the most senior detectives and of course they cover situations on camera where ... maybe somethings won't happen.

The cases featured in the show they almost never actually end up prosecuting anyone without quite a bit of evidence. They're not really the kind of cases you hear about where someone is just prosecuted on hearsay and one bit of evidence and so on, that i'm sure is by design (for the tv show). Detectives show a lot of skepticism about what people too, that was interesting. They follow those leads but those featured seem highly flexible.

I wonder how much of the bad prosecutions / situations are about the prosecutor rather than detectives.
