Packer's crime-control model argues for an expanded role of the courts. Essentially, the punishment should be swift and severe, with an emphasis on processing criminals through the court systems as quickly as possible. Ultimately, crime-control is meant to protect society from the criminal element. The due process model operates under the principle that everyone is innocent until proven guilty. Therefore, each alleged criminal has a right to defend themselves from any accusations and must be given a fair and complete trial.
the crime-control model allows significant possibilities for the ethical violations by law enforcement. As crime must be punished swiftly and severely, there will inevitably be circumstances in which a punishment is administered upon an innocent person.
