A plea agreement is a deal made between a defendant and a prosecutor in a criminal case. In this arrangement, the defendant agrees to plead guilty to a lesser charge or to receive a lighter sentence in exchange for cooperating with the prosecution. This can help both parties save time and resources, as it often leads to a quicker resolution of the case. Plea agreements are common in the legal system and can involve various types of crimes. They are often used to encourage defendants to provide information about other criminal activities or individuals, which can assist law enforcement in their investigations.
