Horatio's One-Liner:
Frank: No kids, no gun. He must have grabbed the knife for self-defense. What the hell has happened here?
Horatio: Frank... it's called Crime Scene Investigation.

When Horatio and Frank are talking to the man who had an affair with the wife of their case victim, we first see a close-angle of Horatio with a small, quite blurry background, but we are able to see a small boat behind him. However, in the next, wide-angle of all three characters/cast members, the background has been extremely enlarged, with a gigantic boat and nothing else (besides the road) visible. That is highly unlikely...
