During booking, a police supervisor records in a registry (or book) the suspect's identifiers and the charges he faces. Police remove and inventory the suspect's property. He is photographed and fingerprinted (with a digital scanner, not ink). Some jurisdictions take saliva swabs for a DNA test. This "pedigree," photo and fingerprints are shared via computer links with state and national crime information centers. (Click here for a sidebar on the NCIC.) Drug and alcohol tests can be given during the booking process.
