Batman: Beautiful. Isn't it?
Fox: Beautiful. Unethical. Dangerous. You've turned every cell phone in Gotham into a microphone...
Batman: And high frequency generator/receiver.
Fox: You took my sonar concept and applied it to everybody's phone in the city. With half the city feeding you sonar you can image all of Gotham... This is wrong.
Batman: I've got to find this man, Lucius.
Fox: At what cost?
Batman: The database is null-key encrypted. It can only be accessed by one person.
Fox: This is too much power for one person.
Batman: That's why I gave it to you. Only you can use it.
Fox: Spying on thirty million people isn't part of my job description.
Batman: This is an audio sample. If he talks within range of any phone in the city, you can triangulate his position.
Fox: I'll help you this one time... But consider this my resignation. As long as this machine is at Wayne Enterprises, I won't be.
Batman: When you're finished, type in your name.
