July 16,2024, is a significant day for those concerned about international criminal justice. Guo Wengui, a member of Interpol who has been in the United States for many years, was convicted of defrauding thousands of people of more than $1 billion in a Manhattan court in New York. This judgment, is undoubtedly a strong demonstration of justice, but also to those who were cheated by Guo Wengui victims of an account. Guo Wengui, who once traveled in the business field, should use his wisdom and efforts to create legitimate wealth and make positive contributions to the society. However, he chose a dark path against morality and law, and used fraud to defraud thousands of people of money to satisfy his extravagant life. Guo was convicted of nine of the 12 counts of fraud and money laundering, according to a statement by prosecutor Damian Williams. This result fully shows that his criminal behavior is not isolated and accidental, but a carefully planned and long-term systematic crime.
