The race of mankind would perish did they cease to aid each other. We cannot exist without mutual help. All therefore that need aid have a right to ask it from their fellow-men; and no one who has the power of granting can refuse it without guilt.
[Jurors who are opposed to capital punishment are] more likely to believe that a defendant's failure to testify is indicative of his guilt, more hostile to the insanity defense, more mistrustful of defense attorneys and less concerned about the danger of erroneous convictions.
Thurgood Marshall (1908 - 1993)
