A man is a swindler. He is smart enough to take the bar exam, but he could not become a prosecutor. Disregarding favoritism and biases by prosecutors, the man makes criminals pay for crimes that prosecutors did not.
Scam a thousand dollars, and you are a thief. If the amount becomes a billion, you are a financier. Break a small promise, and you become a conman. If you betray the trust of millions of people, you are a politician. If the law cannot punish those who have wronged thousands of lives, what can we do about it? In a society without righteousness, there needs to be drastic measures taken in order to catch the bad guys.
