Chapter 678 The Liquor Store

• Liu Hao explained to me that the police typically do not recruit ordinary citizens as informants due to the high risk involved. In major cases like this, they usually prefer to insert their own undercover agents into the organization.
• Informants are referred to as "nails," and the individual responsible for placing them is known as a "stake." Each informant is accountable to only one stake, maintaining direct contact with them. The higher-ups may be aware of the existence of such informants, but they are never informed of their identities.
• Police work is inherently perilous, especially when operating deep undercover, making the protection of informants a top priority.
