An undercover police officer is using an informant in order to be introduced to a local drug dealer. Just prior to the operation, the informant, a convicted drug dealer himself, failed to meet the officer and purchased drugs without the officer present. The informant turned over the drugs to the officer immediately after the transaction. What problem does this situation exemplify when dealing with informants?
◦ Informants are highly motivated to "get the job over with" and often have difficulty waiting.
◦ Informants are difficult to control.
◦ Informants may be a source of embarrassment to the department.
◦ Informants have questionable credibility in court.
