Informants are a huge and important tool for criminal investigations, these are some of the advantages and benefits of using them:
- Obtaining useful information: The main "task" of informants is to provide useful information to the investigators so that, they solve investigations quicker, stop a possible crime from happening and arrest the delinquents.
- Help to create an arrest plan: With the help of the informants, the authorities can have a plan in order for them to arrest the person they have been investigating for a while.
- Help to know more about the criminal investigations: If there is a new investigation and they don't have enough information, informants are the most important tool here because they will give confidential information about the person or organization the authorities are investigating.
