CSI: NY, Season 7

Mac Taylor:
Uncovering mistakes made by your lab and alerting defense counsel was part of your oath. Still is.

Jo Danville:
Tell that to Senator Matthews. I still get letters from him blaming me for the outcome of his daughter's case. The mistake I uncovered was made by a guy named Frank Waters. Impeccable reputation. I worked with Frank Waters for 12 years, Mac. I went to his wedding, his kids' birthdays. So when I discovered he destroyed a document detailing a mistake he made interpreting DNA results, trust became just another word and Serena Matthews' rapist went free.

Mac Taylor:
You had to make it public.

Jo Danville:
It was a decision I don't regret making and I'd make it again.

Mac Taylor:
Jo, my team does not sacrifice integrity for a desired result. Now that you're part of it, I promise you you'll never have to make that kind of decision again, okay?
