Homicide: Life on the Street, Season 4

Pembleton:
And I broke the first rule of being a detective. I assumed that Zeke Lafeld was homosexual.

Bayliss:
Well, it's what people do, Frank. It's human nature.

Pembleton:
Yes, it is human nature to kill someone simply because their sexual orientation is different.

Bayliss:
People get afraid. Threatened.

Pembleton:

Bayliss:
As adults we get socialized. We learn to behave.

Pembleton:
No, no, no. We learn to hate.
