Criminal justice is known to be the system exercises, and institutions of government mandated to sustain social control, discourage and lessen crime or sanction those violating the law through rehabilitation and subjecting them to criminal penalties. People who are accused of crime also have constitutional protections from abuse of prosecution and investigatory powers (Abdolsalehi, 2013).

Criminal justice system entails three parts that are:

1. Law enforcement (FBI, police officers, homeland security department among others),

2. Courts,

3. Corrections (probations, prisons, jails, etc.) in this system the first encounter that the accused or the defendant is usually by the police who take charge in the investigation of the suspect’s wrongdoing and arrest.

The suspect is arrested and arraigned in court for prosecution where the judges of the court follow the due jurisdiction. If the offenders are found guilty they are turned over to the correctional institutions and authorities where the administrations of punishment are different forms depending on the crime committed.

The Federal Bureau of Investigation (FBI) of the United States is charged with a mission of equipping the national security, law enforcement and intelligence community associated with the criminal information needed to protect the U.S. when preserving the civil liberties (Bivol, 2013). The FBI developed National Data Exchange (N-DEx) system designed idea from experts of subject matter. The FBI looked for input from state, local and federal agencies resulting in an excellent system.

This is a system that contains data incident collection that the local police departments usually record and track information such as date of birth, names, phone numbers, addresses, offenses, license plates, convictions, arrests and so on. When the police share such kind of data information, it makes the investigation work easy. N-DEx helps protect people from terrorism and crime through sharing information within the police departments.
