Definition
An informant is an individual who provides information to law enforcement about criminal activities, typically someone with inside knowledge of crimes, criminal organizations, or illegal operations. Informants occupy a morally ambiguous position—they may be criminals themselves seeking reduced sentences, community members concerned about crime, or individuals with personal grudges against those they inform on. Law enforcement distinguishes between confidential informants (CIs) who provide ongoing intelligence in exchange for payment or consideration, and cooperating witnesses who testify in court. Informants provide crucial intelligence that investigators couldn't obtain through conventional means: details about planned crimes, organizational structures, locations of evidence, and identities of participants. However, informant information must be carefully verified, as informants may lie to serve their own interests, settle scores, or tell investigators what they want to hear. Managing informants requires balancing their value against the ethical complications of working with criminals and the legal requirements for protecting their identities.
Historical Context
Informants have been used in law enforcement since ancient times, but modern informant systems developed in the 19th and early 20th centuries as police forces professionalized. The Pinkerton Detective Agency pioneered systematic use of underworld informants in the 1850s, paying criminals for information about other criminals. By the 1940s noir era, informants had become essential to detective work, particularly in investigating organized crime, vice operations, and political corruption. The period saw informal networks of informants—bartenders, cab drivers, street hustlers, and small-time criminals—who traded information for cash, protection, or leniency. Detectives cultivated relationships with informants over years, meeting in back alleys, diners, and dark bars to exchange information. The noir era lacked formal regulations governing informant use, allowing detectives wide latitude in making deals and protecting sources. This created opportunities for both effective crime-fighting and serious abuses, as informants could manipulate the system and detectives could use informant claims to justify questionable actions.
In Detective Work
Modern law enforcement maintains sophisticated informant management systems with formal protocols, documentation requirements, and oversight mechanisms. Detectives recruit informants through various means: offering reduced charges or sentences to arrested criminals, paying for information, providing protection from threats, or appealing to civic duty. Effective informant handling requires building trust while maintaining professional boundaries, verifying information through independent sources, and protecting informant identities to prevent retaliation. Detectives must document all informant contacts, payments, and information provided, creating a record that can be reviewed if the informant's credibility is challenged in court. High-value informants may be placed in witness protection programs if their cooperation puts them at serious risk. However, informant use remains controversial: informants may commit crimes while working for police, their information may be unreliable, and the promise of leniency can incentivize false accusations. Recent cases have exposed problems with informant testimony leading to wrongful convictions, prompting reforms in how informant information is corroborated and disclosed.
In Noir Fiction
Noir fiction portrays informants as tragic figures caught between criminal worlds and law enforcement, trusted by neither and despised by both. The classic noir informant is the small-time criminal who trades information to stay out of jail, the bartender who overhears too much, or the desperate person who informs to settle a personal score. Films like "The Maltese Falcon" and "On the Waterfront" feature informants as morally complex characters whose cooperation comes at tremendous personal cost. The noir detective's relationship with informants is transactional but often tinged with sympathy—both operate in moral gray zones, both are used by larger forces, and both understand that loyalty is a luxury neither can afford. Noir explores the consequences of informing: the informant found dead in an alley, the family threatened by those he betrayed, the detective who must protect a source he doesn't trust. The term "rat" or "snitch" carries particular weight in noir's underworld code, where informing is the ultimate betrayal. Yet noir also recognizes that without informants, many crimes would never be solved, creating a moral tension between the necessity of informing and the code against it.

His cooperation, while motivated by self-interest, dismantles a criminal network.
Organized Crime Case: An informant within a crime family provides the FBI with detailed information about illegal operations, leading to RICO charges against the organization's leadership. The informant enters witness protection after testifying, leaving behind his former life entirely. Years later, his identity is compromised, demonstrating the permanent risks informants face.
