Slowly, as the play develops, the members of the jury do become a team, examining the evidence and doing their duty as jurors. Juror #8, of course, is the one man who prevents a grave injustice when he refuses to vote before considering the evidence. After he takes his stand, one by one the other jurors become engaged in the search for justice. The final hold out eventually joins the others in voting "not guilty." I think they did accomplish their job, finally, by examining each piece of evidence and asking the right questions. The prosecution did not prove beyond a reasonable doubt that the boy killed his father. The evidence was not conclusive, and some of it was very weak or contradictory.
