12 Angry Men1957

Juror #8:
Look, there was one alleged eye witness to this killing. Someone else claims he heard the killing, saw the boy run out afterwards and there was a lot of circumstantial evidence. But, actually, those two witnesses were the entire case for the prosecution. Supposing they're wrong?

Juror #12:
What do you mean, supposing they're wrong? What's the point of having witnesses at all?

Juror #8:
Could they be wrong?

Juror #12:
What are you trying to say? Those people sat on the stand under oath.

Juror #8:
They're only people. People make mistakes. Could they be wrong?

Juror #12:
Well, no, I don't think so.

Juror #8:
Do you 'know' so?

Juror #12:
Oh, come on. Nobody can know a thing like that. This isn't an exact science.

Juror #8:
That's right, it isn't.
