How inaccurate does an estimation have to be before it becomes a lie? What happens when a bank teller asks me during a credit application how many assets I have and I estimate about 10 billion bucks, when it later turns out I own the three dollars in my wallet and a strip of chewing gum? Am I (criminally) liable in that case?
