If you are a police officer, there is no doubt sometime in your career you will work with a confidential informant. Whether you’re trying to crack a difficult case, gain key evidence in a conspiracy investigation or trying to learn about criminal activity before it happens, usually you will need to cultivate relationships with confidential criminal informants. Unfortunately, most agencies lack sophisticated systems for managing confidential informants, and they rely on rudimentary spreadsheets and notes on scraps of paper locked away in file cabinets. This archaic way of managing informants is not because technology doesn’t exist to modernize the process; it is because officers are trying to protect their informants’ identities from being divulged.
