Castle, Season 5

Beckett:
I don't understand what a car driving through the desert has to do with Dale Tanner.

Warburg:
[holding the photo up] Intelligence reports said there were three high-ranking Afghan militants in this car. It was the right make and model, traveling at a high rate of speed. So the drone pilot was given the green light to strike. But then, he saw those red dots on the trunk, and he had a feeling. So he aborted the mission. There were no militants in that car. The red dots were roses; because the young couple driving down that desert road had just gotten married. That's when I knew I could no longer be a part of the drone program.

Castle:
But I don't understand why. The pilot didn't fire.

Warburg:
Because the next generation of drones won't have pilots. The new AI software will give drones decision-making capability. They'll assess the data and take lethal action all on their own.

Castle:
Really will be rise of the machines.

Warburg:
Those new drones would turn that car to ash without hesitation. That's why, when lives are at stake, we need a man who sees roses. We need the human factor.
