CSI: NY, Season 2

Det. Mac Taylor:
There are three things that I'll protect at any cost: the honor of this country, the safety of this city, and the integrity of this lab. As scientists, we have a great deal of power, the ability to assign guilt or innocence. But when we analyze a crime scene, we collect pieces of evidence, we make a promise to the people of this city. A promise to handle that evidence with respect, integrity, and good faith. When you broke the seal, you broke that promise.

Detective Aiden Burn:
I didn't do it. I didn't plant the evidence. I wanted to. Man, I wanted to, but I couldn't go through with it. I knew I couldn't live with that.

Det. Mac Taylor:
Is it that you couldn't live with it, or you couldn't compromise the integrity of this office?

Detective Aiden Burn:
You know how much this place means to me, Mac. But that son of a bitch raped Regina twice, and he's gonna get away with it twice?

Det. Mac Taylor:
And if the credibility of our findings is suspect, how many more do you think will walk? Ten? Twenty? A hundred? Truth is, Aiden, I can't have someone like that working in this lab. You're fired.

Detective Aiden Burn:
[handing over her badge] Truth is I can't do this anymore, Mac. I mean, I got to be honest with you. If somethin' like this ever happened again, I don't think I'd trust myself. And I'm sorry I let you down. Just do me a favor, huh? Catch this guy for Regina.

Det. Mac Taylor:
I will. This folder... will be right here on my desk till we get him.
