There's an excellent episode of the First 48 where a totally innocent guy has a bunch of circumstantial evidence against him and almost gets charged with murder because of that evidence and not getting council and shutting up.  Happily, for that guy, the cops found a much more likely suspect and shift their focus.  I wish I could remember the episode name or number because it's almost perfectly why someone innocent can look pretty suspicious and by talking dig themselves into a huge hole.

That’s episode 1-124 😂 

The best ones are the New Orleans detectives who always without fail take the perp to smoke. Dude never sees it coming.
