A former New York City police sergeant charged with acting as an illegal Chinese agent for allegedly intimidating a U.S.-based fugitive from China went on trial on Wednesday and argued he did not know that country's government was behind a private surveillance job he took.
Federal prosecutors in Brooklyn say Michael McMahon pressured a New Jersey resident, Xu Jin, to return to China to face bribery and embezzlement charges, one example of a global repatriation campaign by Chinese law enforcement known as "Operation Fox Hunt."
