In general, you may only obtain records concerning yourself, deceased individuals, or living individuals who have given you their permission to obtain their records. Most states have a statewide agency that acts as a clearinghouse for all statewide arrest information. These so-called "state rap sheets" are usually much more detailed than the Interstate Identification Index; usually listing not only the arrest information, but the subsequent court action following that arrest. The National Law Enforcement Telecommunications System (NLETS) is an interface to search each state's criminal and driver records as well as the License Plate Reader (LPR) records going back one year maintained by the U.S. Customs and Border Protection (CBP). Thus through NLETS, a law enforcement agency in one state could search for someone's criminal and driver records in another state. NLETS potentially serves as a better tool to search for minor misdemeanors and traffic violations that would not be in the NCIC. In the United States, criminal records may be expunged, though laws vary by state. Many types of offenses may be expunged, ranging from parking fines to felonies. In general, once sealed or expunged, all records of an arrest and/or subsequent court case are removed from the public record, and the individual may legally deny or fail to acknowledge ever having been arrested for or charged with any crime which has been expunged. However, when applicants for a state professional license or job that is considered a public office or high security (such as security guard, law enforcement, or related to national security) must confess if they have an expunged conviction or else be denied clearance by the DOJ. With few exceptions, there is no post-conviction relief available in the federal system other than a presidential pardon.
