This is not talking about a mistaken witness, but one that intentionally makes a false statement in order to use the courts to murder an innocent person.
With respect, you can't know that. Diligent inquiry and then some is made by two counsel (at least) in a capital case with strong agendas in play. And even so a not insubstantial number of men have been convicted of crimes they didn't commit in part on the testimony of witnesses who mostly believed what they thought they saw. Relatively recent development in forensics is helping undo much of it.
I believe that God gave the dietary restrictions for health reasons, not because pigs are evil.
So do I, but He couldn't have explained the medicine of it. It would be gibberish to them. So he didn't. He put in the rule that served their situation best.
No, you still are not being clear enough.
There's literally no way to be clearer than:
"People who are put to death for a crime they didn't commit."
Or following an answer to your:
The person that was falsely accused and escaped execution when the false witnesses were exposed?
With: "No, the person "put to death swiftly" where the error or willful deception was discovered after the fact, which is when it almost always is, on appeal. An appeal you wouldn't have in play."
There are two sets of people that could be put to death.
I've addressed both in any event. I noted that you're encouraging people to not bear witness, given they have to know they could be mistaken and the consequence of that.
You're also relying on the least reliable means we currently have to convict someone of a capital crime.
And you're encouraging rapists to be murderers.
And you're making it almost impossible to preserve those who are innocent of the charge given that discovery of contradictory evidence to that testimony would mostly come after the wrongly convicted was put to death.
Now as horrible as that was, there was a time when it was simply the best that could be mustered. Now it isn't.
The person accused of the crime and the false witnesses.
The person whose testimony is later shown to have been wrong, through honest error or willful misrepresentation. And who can know which is which? Again, I don't believe you'll find an exception/mitigation on the point but feel free to note/cite it for my edification if it exists.
Then there is no real way of finding anyone guilty of any crime.
There's no reason to believe that at all. In fact, we have a number of ways to be more certain, from DNA to rules of evidence designed to prevent fraud through mistake or coercion or malicious intent and an appeal system to make sure there's no abuse of discretion and to weigh subsequent exonerating evidence.
You have successfully abolished the entire court system
Not at all.
