The National Institute of Justice (NIJ) funded the development of the publication, which involved a 3-year effort that consisted of a market survey of hardware and software, literature reviews, Internet searches, and meetings with subject-matter experts (some experienced in cell phone forensics) and skilled technologists. The main conclusion of the publication is that corrections administrators should implement forensics in their facilities, so they can obtain evidence of criminal acts from illegal cell phones possessed by inmates. The guide argues against the common practice of disposing of illegal cell phones confiscated from inmates. Instead, the phones should be subjected to the latest forensic methods for examining cell phones for evidence of criminal behavior. Also, data on these phones can assist in identifying links between inmates and individuals in the community who could then assist in identifying corrections officers and civilians who smuggle the phones into the facilities. The guidebook provides links to sample policies and procedures, including summaries of successful prosecutions based largely on cell-phone evidence. Given the number of inmate cell phones confiscated, the guidebook suggests that select correctional staff be trained in cell-phone forensics and be equipped with state-of-the-art software for obtaining and analyzing the contents of various types of cell phones.
