If an informant reveals to a police that customers of a particular public bar occasionally do lines of cocaine on the tables positioned in alcoves, the officer won't require a warrant.
A person who gives an agency confidential information about a person or group is known as an informant (also known as an informer). The phrase is frequently used in the context of law enforcement.
The courts effectively have no control over the way that the police use informants. Three Supreme Court rulings from the 1960s—Hoffa v. United States, Lewis v. United States, and Osborn v. United States—made it plain that police can utilise informants with certain latitude.
