Jurors are supposed to remain unbiased and open minded when dealing with a defendant, however some jurors do not. In the play 12 angry men written by Reginald Rose jurors 10 and 3 are examples of bad jurors because they both show heavy bias against the defendant. In the book 12 angry men jurors play a key role in whether the defendant lives. One example of a poor juror is juror 10. Juror 10 is rude and prejudiced against the defendant because of where he came from. He says multiple times throughout the book where he shows based against the defendant because of personal reasons.
