In the Court of Law #3 (Solution)

How? Have you got the answer? Let’s compare with mine!

In this complex situation, we must convince the court that we didn’t commit the crime, no matter whether we were a truth teller, liar, or normal. So, we have to make a statement which proves it.

“A truth teller didn’t commit the crime” –it prove it if only we were a truth teller or a liar, just like explanation in previous cases.

But, what if we were normal? Can it prove, too? Let’s check it!

No matter whether we’re a truth teller or a liar, it can prove. What about normal? Normal means that we can reverse whenever we want. In other words, we could be a truth teller or liar. It’s similar to our first-two conditions (true truth teller or true liar). Means, it can prove, too.

So, a sentence which can prove our innocent is “A truth teller didn’t commit the crime.”
