The year is 1930 in a small community in the south-west USA. A white woman has been raped and a black man has been accused. There's a furious mob rioting, demanding a hanging. You(white, not-racist) have been asked to testify and your testimony is deciding. You know the man is innocent. You know they'll hang him if he's found guilty. You also know if you say he's guilty it will stop the rioting completely thus saving the other negro folk in the community from the wrath of the mob and there's even a good chance it will save other people's life.

a) guilty
b) not guilty
