Yeah that’s literally how they write the episodes - whatever the most fucked up sexually violent thing that ( emphasis here ! ) happens to a real person in real life that is reported in the news, the writers room figures out a fun way it could have happened in a way that lionizes the cops and shows them as heroes. It’s the entire point of these shows, which make up at least 20% of all network TV.

Edit:

Forgot to mention that sometimes, of course, the cops need to be allowed to “bend the rules” to solve case and deliver justice. We are meant to believe their corruption is what makes it fiction.
