A Man Alone (1955)
Dr. Mason: Gil, doctors take an oath, as well as Sheriffs. And there's a reason for both.
Dr. Mason: One has to do with saving lives - no matter what I think about a man. That's why I told them he has yellow fever.
Dr. Mason: The other binds you to uphold the law, by due process. To protect an accused man against illegal violence no matter what you think of him.
Dr. Mason: It's a principle that's more important than that man, or Nadine, or me, or Nadine.
Dr. Mason: You can't give him to that mob.
