Undercover ops, also known as 'STINGS', are operations conducted by law enforcement agencies in which undercover agents or informants are used to investigate and apprehend criminals. These operations involve the use of deception and disguise to gain access to criminal activities and networks. STINGS are often used to target drug dealers, organized crime, and other high-level criminals. They can also be used to investigate white-collar crimes such as fraud and embezzlement.
