Is NLETS criminal history record information always use a substitute for the NCIC interstate identification index?

No, NLETS (National Law Enforcement Telecommunications System) criminal history record information is not always a substitute for the NCIC (National Crime Information Center) interstate identification index. While NLETS provides a platform for sharing information among states, it does not contain the same comprehensive criminal history records as the NCIC. Instead, NLETS facilitates the exchange of information, whereas NCIC serves as a national repository for criminal history data. Law enforcement agencies often use both systems for different purposes.
