Person of Interest2011

Harold Finch:
When the towers came down, you were in a hotel in Mexico. I was here. I was working. Didn't even know about the attacks until that evening. You see, Mr. Reese, until that day, I had spent the better part of my life making myself very rich. Suddenly all that money didn't seem to amount to much. [pauses, then continues the story]

Harold Finch:
After the attacks, the government gave itself the power to read every email, listen to every cell phone, but they needed something that could sort through it all, something that could pick the terrorists out of the general population before they could act. The public wanted to be protected. They just didn't want to know how they were being protected. So when they finally got a system that worked, they kept it secret.

John Reese:
So how do you know about it?

Harold Finch:
I built it.
