12 Angry Men

In the movie "Twelve angry men" an eighteen year old is charged with the murder of his father. At first, all the jurors believe that he is guilty beyond a reasonable doubt, except for one, who believes that they owe the boy more than five minutes in deciding if he lives or not. The man who does not believe that the boy is guilty explains his views to the rest of the jurors and is …

…people took one look at him and thought one thing, guilty. If the presumption of innocence is not taken in to account by even one juror then there wouldn't be a fair case. Where here in the movie, at least this one man in the jury took into consideration the presumption of innocence, because he knew that the real purpose of the justice system was to lay out facts and give everyone a fair chance.
