Re: visuals?
Columbo told the story from the perp's view.
CSI and later procedurals are really easy to predict by the 'bigness' of an actor, though. A well-known name with just a two-sentence witness statement in the second act? Guilty. Will come back in the last act.
Unknown actor gets grilled for three pages of script and has all evidence against them? Nope, they're not it.
