The Mentalist, Season 1

The Mentalist (2008-) is an American crime procedural television series about a private investigator who uses his skills of observation to help the police solve crimes.

If we're lucky, we'll find a murder weapon. It was obviously a well-planned robbery.

Why is that obvious?

Nobody finds themselves in a locked room full of old masters in the middle of the night by accident, do they? So, well-planned.
