Bad Day at Black Rock1955

Sheriff:
Let Smith find himself a new boy. I can't take it another day. Four years ago, if I'd of done my job, if I'd of checked up and found out what happened. But I didn't! It was just like Smith figured...I didn't even try to find out. Don't you understand? You know, when you wear this badge, you're the Law. And when somebody does something against the Law, then you're supposed to do something about it. Me - I did nothin'. That's what's eatin' me. What kind of prescription you got for that?

Doc:
I don't know. I haven't found one for myself. But there's one thing, Tim, don't quit.

Sheriff:
Why not?

Doc:
Because maybe this feller Macreedy's got the prescription.
