More Fun with Jewish Law
9th December 2009
David Friedman is always worth reading.
Witnesses, in this case or others, might lie. In other cases, one thing discouraging them from perjury is that if it is discovered that their false testimony led to the execution of an innocent defendant, they will be found guilty of murder and themselves executed. But if their testimony leads to the execution of an innocent defendant who is himself dying of a lethal disease, they won’t be executed, because killing someone who is dying of a lethal disease isn’t murder.
Since the witnesses are not at risk of execution for perjury, they might commit it, so their testimony can not be trusted—cannot be taken as sufficient evidence to convict someone of murder. So if someone who is himself dying of a lethal disease commits murder, and doesn’t do it in the presence of the court, he cannot be convicted.
Do that twelve hours a day for three years. Congratulations! You’ve just been through law school.
