It is not self-evident to someone who is emotionally or intellectually invested in finding someone guilty. However, even if one is certain that Amanda and Raffaele are guilty, he or she should still ultimately check an impulse to disregard legal or forensic precedent.
William Roper: So, now you give the Devil the benefit of law!
Sir Thomas More: Yes! What would you do? Cut a great road through the law
to get after the Devil?
"William Roper: Yes, I'd cut down every law in England to do that!
Sir Thomas More: Oh? And when the last law was down, and the Devil turned
'round on you, where would you hide, Roper, the laws all being flat? This
country is planted thick with laws, from coast to coast, Man's laws, not
God's! And if you cut them down, and you're just the man to do it, do you
really think you could stand upright in the winds that would blow then?
Yes, I'd give the Devil benefit of law, for my own safety's sake!"
