In the beginning of 12 Angry Men the jury votes eleven to one that the man on trial is guilty of murdering his father. The eleven that voted guilty had no doubt in their mind that the man on trial was not guilty and they had trouble believing that the one man that voted innocent thought otherwise also. This man, who stood alone in a hot heated jury room, used many different tactics and angles to help get his points across and get a vote of not guilty. The jury leader suggested that each jury member tell Jack Lemon why they thought the boy was innocent.
The first point that Jack Lemon shot down was the point made about the knife. The one gentleman stated that the knife was one of a kind and then went on to say the store that the boy said he bought the knife from did not remember him purchasing it. At this point Jack Lemon pulls out the exact same knife and slams it on the table causing the other jury members to see that the knife was not one of kind. This was the point that showed the other jury members that their might be other things that might have some skepticism surrounding the evidence against the boy on trial. .
Another point that one of the jury members made was that the old man downstairs heard the boy yell that he was going to kill his father. Jack Lemon then goes state that how many times have you said that you kill someone out of anger it mean that you were really going to kill someone. Jack Lemon goes on to argue this point with one of the jury members and frustrates the man. At this point the man becomes very aggressive and shouts out in a rage that he was going to kill Jack Lemon. Everything stops and the man says that Jack Lemon tricked him into saying that but the point was already made. The point was that people can say things in a fit of rage that they don't really mean and everyone in the room understood that.
One more point that found was really important Jack Lemon's character made was the fact that the boy could not remember what movie he saw.
