Writing Computer Desk

I have a question of computer crime detectives?

Do computer crime detectives just work to solve computer crimes behind their desks or do they ever go out to catch the criminal who’s committing the computer crime? or do other officers do that? Please answer, because I’m writing a book and I’ve been trying to find a part of the law that hasn’t been used before on television. thank you for your help.

detectives usually put a case together against a suspect, and officers make the arrest…
