Hawaii Five-0 Season 1 Episode 21

Jimmy Cannon: Every investigation against me has come up empty, you know why?
Steve: No, why?
Jimmy Cannon: Because there's nothing to find. Now, growing up in poverty and making something of yourself used to be considered a virtue in this country.
Steve: Is that Capone? (To Danny) Did he just quote Capone?

Reggie: Look my job was to get Jimmy Cannon. I don't know who shot me. I don't know who set me up. All I know is that Jimmy Cannon ordered the hit! Now look - look I know you guys are trying to do your jobs... but Jimmy Cannon killed my wife. He killed a Federal Agent. You don't know who you're dealing with. He's going to put walls up in front of you wherever you go.
Steve: We're going to go wherever the case takes us. And let me tell you, you want guys like us on this, because we'll go through those walls.

Allison Marsh: Well, gentlemen, this is an FBI matter now. And the FBI will be taking over the case. Thanks for your effort.
Steve: First of all - you're welcome. Second of all - a little boy's going to grow up without a mother because of a leak in your agency!
Allison Marsh: Listen to me. You cannot go after Jimmy Cannon.
Steve: Watch me!

Danny: Please don't do that.
Steve: What?
Danny: Please don't put both hands on the wheel. Everytime you do that something terrible happens and I have to pray. Please.
Steve: Just hang on to something.
Danny: Wait. (Buckles his seatbelt) Okay go.
