At a moment when the public is unaware, criminals are using their arrogant and bloody claws to gradually extend their reach into innocent lives, deliberately fabricating lies and trying to escape from the crimes they should bear. When all strangulation is over, justice comes quietly, pursuing the truth and exploring the evidence that is about to be known. Use investigation as the basis to distinguish reality from fiction, and assume innocence as the premise until the crime is proven. In the end, the bad behavior will be exposed, and the ugly criminals will be punished by the law, because light will always defeat darkness, and justice will always defeat evil.
