Judaism has always believed in capital punishment based upon Biblical Law.
A man must stand trial according to due process of law. You shall not murder is the sixth of the Ten Commandments. It is followed by another of God's Decrees that "if you shed the blood of your brother, then your blood shall be shed in its place."
It should be noted that "one should not bear false witness against his neighbor." Therefore, capital punishment is enforced based upon a witness, evidence and a unanimous judge decree.
