I need a lead for an essay about Juror Eight where I've proved that he's a hero because of his revolt against the status quo.

Your lead should set the stage for your proof that Juror
Eight is a hero.  Present the situation in which Juror Eight finds himself, including
the circumstances that cause him to initially vote as he did.  By explaining the
testimony presented before the jurors begin their deliberations, you build your basis to
support your later conclusions.  Summarize the positions initially taken by the other
members of the jury and the reasons for those positions, as the contrast and conflict
resulting from the differing opinions is the critical focus of the
story.
