The novel '12 Angry Men' written by Reginald Rose is about a young boy who is being accused of murdering his father. 12 jury men are sent into the jury room where they are left to decide whether or not the boy is guilty or not guilty for the death of his father. The jury men, after hours on end of going thoroughly through evidence they come to conclusion that the boy is innocent. Is the boy really innocent? There were two witnesses, the boys knife impaled into the fathers chest, and other little bits of evidence that proves he is guilty. The evidence were facts to the crime meaning it was truth. Although the boys actions did make it look to be he murdered his father,there were perceptions of the boy for example: - Juror 4 says "We're here to decide whether he's guilty or innocent of murder, not to go into reasons why he grew up this way. He was born in a slum. Slums are breeding grounds for criminals. I know it. So do you. It's no secret. Children from slum backgrounds are potential menaces to society. Now i think..." - When the old man (first witness) heard the boy hoot "I'll kill you!" He assumed the boy killed his father, but in the jury room when juror 3 says "let go of me, god damn it! I'll kill him! I'll kill him!" juror 8 replies "You don't really mean you'll kill me do you?" proving that when someone says they'll kill someone they don't always actually do it. These two examples among many show perception in the novel, the first example provided tells us juror 4 perceives the boy to be guilty purely based on where the boy lives and what his idea of the neighborhood is like and how the people are there. His perception of where the boy lives is his main evidence of the boy's actions. The second example provided is the perception of juror 8. Juror 8 believes the boy is innocent for many reasons one being that when the boy hooted "I'll kill you" that he may not have actually killed his father as people on a daily basis when they are mad hoot "I'll kill you" or "I want to kill you" but don't actually do it. Therefore that is juror 8's perception of whether or not the boy actually killed his father or not.
