NCIS: Naval Criminal Investigative Service2003

Special Agent Leroy Jethro Gibbs:
They've got to be after the president. What would killing the ball carrier give them?

Agent Caitlin Todd:
Nothing. Another aide steps in.

Special Agent Leroy Jethro Gibbs:
[realizing] And another plane. This plane. They forced the president to fly his backup.

Agent Caitlin Todd:
Well, security's exactly the same.

Special Agent Leroy Jethro Gibbs:
But the plane isn't. And I'll bet security isn't either until the president's on board. Al-Qaeda has to have planted something on this plane.

Agent Caitlin Todd:
Okay, it can't be a bomb. They would have detonated it by now.
